hi it's katrina
number 10. taprom temple
built during the late 12th and early
13th centuries in what is now siem reap
cambodia the temple known today as ta
prom originally went by the name
rajavihara it was founded by the khmer
king jaya varman vii as a buddhist
monastery and university at its peak it
was home to more than 12 500 people with
another 80 000 living in the surrounding
region the temple was impressively
wealthy possessing gold pearls silks and
other riches it underwent numerous
expansions and additions until the end
of the 15th century when the khmer
empire fell and it was ultimately
abandoned taproom sat alone and
forgotten for centuries when efforts to
restore the temples of angkor began in
the early 2000s it was decided that the
temple would be mostly left the way it
had been found work was done to
stabilize the ruins and maintain their
deserted appearance
over the years tapra merged with the
jungle and became covered in growing
root systems it appears to have been
reclaimed by nature but the overgrowth
is closely maintained to make the site
accessible to visitors there is a poetic
nature to this grand ruin first with
humanity conquering nature to swiftly
create and then nature once again
conquering humanity to gradually
dismantle tab prom is an incredible
reminder of the awesome abundance and
power of the jungle
number 9. ancient tunnel at teotihuacan
after heavy rainfall in 2003
archaeologists working in the pre-aztec
city of teotihuacan outside mexico city
found a three-foot wide sinkhole at the
foot of a pyramid called the temple of
the plumed serpent in it archaeologists
discovered what appeared to be a
man-made tunnel it had been blocked off
on both ends by large boulders the
following year a team led by
archaeologist sergio gomes used ground
penetrating radar to scan the earth they
found that the tunnel measured 330 feet
and ended at the center of the temple of
the plumed serpent it was sealed off
around 2000 years ago and it seemed like
it was done with the intention of never
opening it back up the team began
excavating in 2009 at the painstaking
pace of just a few feet per day they
unearthed seashells pottery cat bones
human skin fragments knives objects made
of amber necklaces figurines wood and
more the items were very deliberately
placed and appeared to be offerings it
was clear that the tunnel was not a
place for average residents of the
ancient city at the end of the tunnel
was a chamber filled with jewelry and
two sculptures facing the entrance it
resembled the type of place where a
priest might go to carry out special
ceremonies some experts believe that
teotihuacan was designed to resemble the
universe if that's the case then perhaps
the tunnel represents an underworld or a
realm of the dead and maybe the statues
inside the chamber symbolize the
creators of the universe
but this is just one of many different
interpretations of the city which
remains shrouded in mystery to this day
why do you think this secret tunnel was
covered up two thousand years ago let me
know your theories in the comments below
number eight naurus
there's an ancient town in northern
france consisting of two miles of
tunnels and more than 300 rooms sitting
roughly 100 feet beneath a forested
plain this place is known as naurus and
it was built starting in the 3rd century
as part of a roman quarry and expanded
into an entire underground village
during the middle ages when people
increasingly sought refuge from violent
wars and invasions at its peak the
hand-dug settlement had enough room to
accommodate 3 000 residents it was
filled with chapels stables bakeries
wells and several town squares the oven
chimneys inside the bakeries were routed
into ground level buildings to prevent
enemies from seeing any signs of human
activity nearby
people eventually began to move above
ground as it became safer to do so and
at some point the nauru's caves were
sealed off and forgotten about this
settlement was rediscovered in 1887 and
became a popular sightseeing attraction
during world war one its walls are
plastered with more than 2 000 pieces of
graffiti left behind by allied soldiers
many of whom participated in the nearby
battle of somme
number 7. cave beneath a castle
located in northern poland old sin
castle sits on a limestone crag
overlooking its surroundings it was
built during the mid-14th century for
the local chapter of the catholic church
the diocese of varmya the castle found
itself at the center of battles in
several conflicts including the polish
teutonic wars and the 13 years war it
ultimately fell under the ownership of
the kingdom of poland during the 16th
century today it's in ruins while
studying the site in 2020 archaeologists
realized that there was something
beneath the hardened sediment floor that
they were standing on in an area known
as the lower castle tess revealed that
there was a large cave under the castle
measuring up to 23 feet deep its size is
unknown but there are tunnels branching
off of it the team also found
centuries-old artifacts including a
medieval tile depicting a falcon hunting
at the time the discovery was announced
the team had not yet excavated the cave
but they did have a team of cavers to
help with the dig that sounds like fun i
wonder what they're going to find
number 6. an ancient roman city
on november 23 1980 a 6.9 magnitude
earthquake struck italy's southern
apennines region killing
2914 people and destroying numerous
towns nearly 200 residents died in the
hilltop town of conza de la campagna as
the disaster brought its 1 000 year
history to an end many of the places
that the earthquake destroyed were
rebuilt but conza de la campagna was
left in ruins after bulldozers pulled up
the remnants of kamsa an ancient roman
town that had been hidden beneath the
modern day settlement the earthquake
brought numerous layers of history to
ground level komsa was first inhabited
during the 6th century bc
over the years it gained a reputation
for being hostile toward the romans who
eventually conquered and romanized it by
implementing a forum an amphitheater and
baths the town grew to resemble a
miniature version of rome reflecting the
empire's power and its ability to govern
when the earthquake struck in 1980 the
forum became visible for the first time
in centuries along with the foundations
of two temples
residents began to build over it during
the medieval period covering it with
houses and a church before the disaster
there were occasional signs that there
might be something ancient hidden
beneath them an archaeologist who
visited in 1930 spotted part of a
drainage channel in someone's basement
which once bordered the forum
some homes were built directly on top of
roman marble which explains why the
earthquake destroyed them so easily the
forum is exposed today with the 1980
street level sitting roughly 10 feet
above it evidence of building and
rebuilding can be seen between these two
layers revealing damage from past
earthquakes that had destroyed the town
have you ever felt an earthquake where
were you and what was it like let me
know in the comments below and now for
number five but first want to give a big
shout out to success raphael and daniel
z martin we appreciate you all thanks so
much for supporting this channel if you

number 5. ancient tunnel network
there are several long-standing rumors
and legends surrounding yarnharnam abbey
a house of the former strata florida
abbey in karadigi on wales
one tale claims that there's a secret
tunnel running from beneath the building
to the greenhouse pub in an attempt to
get to the bottom of this and other
stories about the abbey 53 year old dave
standing began a landscape study of the
property in 2010. he identified a water
conduit that runs along the same route
mentioned in one of the rumors about
underground tunnels from the nearby
greenhouse pub to the abbey dave told
the south wales argus that it would be
very dangerous to explore the pathway
which is no longer maintained and
contains decaying organic matter leading
to dangerously high carbon dioxide
levels water levels inside the tunnel
can change quickly when it rains which
is another reason why it's risky to go
inside it most of the legends
surrounding great britain's abbeys
center around hidden tunnels but most
are actually water conduits similar to
what standing discovered beneath the
abbey would you explore these dangerous
tunnels let me know in the comments
below
number 4. mass graves and concentration
camps
many holocaust victims were never taken
to concentration camps but were instead
shot dead near their homes and buried in
mass graves
witness accounts describe how the nazis
rounded up groups of victims ranging
from a few to several thousand people
they made everyone undress and then shot
them to death near an open pit
this happened in numerous places
including what are now the countries of
belarus estonia latvia lithuania moldova
russia and ukraine in recent years
researchers have started searching and
marking these execution sites and mass
unmarked burials relying largely on
witness testimony his search
organization jahad in unum has
identified over 1 900 sites which are
documented online on an interactive map
but witnesses aren't always available to
help after all the holocaust ended 77
years ago and more and more survivors
are passing away from old age plus
jewish law forbids digging up graves
further complicating the search
finding former concentration camps has
also proven difficult since the nazis
raised them before fleeing
nature reclaimed the sites over time
further concealing the atrocities that
happened in them
remote sensing technology has helped
lead to the rediscovery of some of these
properties
including a work and extermination camp
near treblinka poland over 912 000
people were murdered there before the
nazis abandoned the site in 1943. before
they left they destroyed all the
structures including the gas chambers
and crematorium vegetation grew
obscuring any remaining evidence of the
camp using sophisticated remote sensing
sonar and other non-invasive techniques
researchers pinpointed specific places
to excavate since 2010 they have found
unmarked graves as well as bunkers a
kitchen a latrine and terracotta floor
tiles that were used in the gas chambers
archaeologists have also found the
sobibor extermination camp in poland
where more than 250 000 people were
killed after destroying the buildings in
1943 the nazis planted pine trees over
the site
the team located the crematorium and
understood many of the prisoners
personal belongings they also discovered
an unfinished tunnel that prisoners had
started digging in a desperate bid to
escape death for the researchers new
technology had proved invaluable in
learning more about these horrific
places without having to always disturb
them
number 3. stockport village
nestled behind a row of shops in the
english town of stockport the derelict
shopping center known as stockport
village has been closed to the public
for 15 years which doesn't really seem
like a long time but many people are
totally unaware that it even exists
while others have simply forgotten about
it the complex houses the remnants of
the uk's first cannabis cafe which was
opened in 2001. police raided it that
very day but its popularity spoke and
the cafe remained in business until it
was raided again in 2007. today it sits
in disarray and conveniently hidden from
plain sight
the place also consists of a shuttered
bridle shop gift shop and a huge
four-story gym called outline nobody
seems to remember when it closed but it
was set on fire in 2009 and fell even
further into disrepair the buildings are
considered beyond saving and there are
numerous proposals in the works for
demolishing them and repurposing the
property meaning that stockport village
may disappear before some people even
knew it was there
number 2
ancient altar
there is a stone slab pressed into a
back wall in jerusalem's church of the
holy sepulchre which contains etchings
made by pilgrims who visited the site
over many years
during recent renovations the other side
of the eight by five foot stone was
exposed for the first time in centuries
the long hidden part of the slab
revealed looping ornaments it was once
inlaid with pieces of fine marble and
glass according to archaeologist amit
raem who spoke with the jerusalem post
it was an impressive shiny piece back in
its day when it functioned as a
decoration at the front of a medieval
high altar similar decorations have been
found in other roman churches dating
back to the 12th and 13th centuries the
team believes that the newly discovered
altarpiece dates back to 1149
and it was used by catholic clergy after
the crusaders left jerusalem it was used
by the greek orthodox church it was cast
aside and forgotten about after being
damaged in a fire in 1808.
the church of the holy sepulchre is
considered among christians to be the
site of jesus christ's crucifixion and
burial it's one of christianity's
holiest sites and has long been a major
pilgrimage destination for devout
worshipers the decorated altar slab is
just one example of how the church's
appearance has changed over the
centuries
number one secret rooms under the
western wall
archaeologists were digging near the
second temple in jerusalem's old city in
2020 when they discovered a series of
underground rooms beneath the western
wall plaza built directly into the
bedrock beneath the mosaic floor of a
byzantine building the chambers are
connected by carved staircases the team
had initially expected to be
disappointed when they began exploring
the bedrock because they didn't think
there was anything left to find but they
found two rooms and a courtyard which
date back roughly 2 000 years and had
sat untouched for around 1 400 years
there are niches carved into the walls
which likely functioned as storage
spaces shelves lantern holders and door
jambs
several artifacts were found inside the
rooms including a stone mug clay cooking
vessels and a large stone basin that
held water for jewish purity rituals the
complex sits just 120 feet from a site
called the temple mount also known as
haram al-sharif it's considered holy to
both jews and muslims
at the time the rooms were built the
area they are located and functioned as
the city's civic center
there was a public street just feet away
along with a bridge connecting the city
directly to the temple mount the team
announced plans to continue excavating
the bedrock at the western wall to try
figuring out why the subterranean
complex was built it's one of the few
surviving structures of ancient
jerusalem which was destroyed by the
romans in 70 a.d
