Venice, Italy, is called the Floating City. It was built on 112 separate islands, clustered near each other in the Adriatic Sea. It seems like a miracle that an entire city could be built like that, but the secret is in the foundation.
Under the houses, the churches, and the bridge supports, there are 10 million tree trunks buried in the earth, providing a sturdy foundation for the city. Yes, tree trunks! And many of them have been there for hundreds of years!
They are protected from decay by the underground clay. I hope those tree trunks stay strong for many more years.
I don’t know when I’ll get the chance, but I’ve always wanted to visit and take a gondola ride down the canals and under the ancient bridges.
