[00:00:00]A construction mistake [music] accidentally saved this tower.

[00:00:04]Explain the soil mechanics that prevented collapse. [music] The Leaning Tower of Pisa was never meant to lean.

[00:00:10]When construction [music] began in 1173, builders laid shallow foundations on a patch of [music] soft ground made of clay, sand, and silt.

[00:00:19]By the time the third [music] level was completed, the tower had already started to tilt.

[00:00:24]Work stopped for decades because of wars, [music] and this long pause turned out to be a hidden gift.

[00:00:30]As the soil slowly compressed, [music] the structure settled unevenly but gained stability.

[00:00:35]When construction resumed, new floors were built slightly taller on one side to compensate for the tilt, giving the tower its subtle curve.

[00:00:43]For centuries, [music] gravity kept pulling it further off balance, yet the same weak soil that caused the problem also cushioned the structure, preventing a sudden collapse.

[00:00:52]In the 20th [music] century, engineers carefully removed small amounts of soil from beneath the higher side, [music] reducing the lean without changing its character.

[00:01:00]Today, the tower still stands, not in spite of its flawed foundation, but because of it.

[00:01:05]A construction mistake, combined with patient time and soft earth, is what saved one of the world's most famous landmarks.
