Venice was born in the lagoon because
the Lagoon was useful to Venice so
venetians shaped the Lagoon the way they
wanted
[Music]
this environment posed a problem
how could they build on such soft ground
I'm not that heavyweight I weighed 65
kilos
but I'm thinking like this
kilos is around 140 pounds
if the mud can't support this
how could it bear the weight of a wooden
house
let alone one of venice's grand Stone
buildings
[Music]
the solution
forcing wooden poles into the soft mud
these poles don't support the weight
they transform the mud around them
the idea is to do a little experiment
when you plant many poles they compact
the mud between them
the water is pushed out and the
compaction of the mud itself makes the
the mud more capable of supporting
weight
[Music]
it's under the city we
are by using a large number of poles
pack tightly together
[Music]
directly on top they placed wooden
planks
then impermeable Limestone and above the
water line bricks
[Music]
okay you see I'm lightweight more than
him you can also try
okay you see Omari is not sinking
because it's the effect of the pores
that compacts the mud between them so it
changes from more I would say fluid like
to more solid like and the proof of this
is when we put the plank over there
and do the same thing on the mud without
the pause underneath
you see there's a difference
this technology is The Secret of
venice's construction and longevity
and over the centuries they created the
city we see today
