All the buildings in the city were first made of the earth under the water, and they were piled one by one, and this was the foundation, and they were secured, and they were laid on boards, and then they were built, and all the houses there were built in this way. So some people say that Venice is stone above, and forest below. In order to build Venice, the forests of northern Italy were all cut down. Such a house, there is no need to worry about the underwater wood rotten, it will not rot, and it will become harder and harder, the longer.
