text: why doesn't the leaning tower of pisa, in italy, fall over? how can such an old structure lean so much and not fall. if that was my house it would fall in one week. they don't want it to fall. i have been there, they have super huge concrete anchors on one side, and the tower is anchored to them with big metal ties. they have counterweights up on the top of the tower to weigh it in the opposite direction. they tried digging under it to reinforce the foundation, but it almost fell over. you cannot go up in it any more either, that was a bummer.
