Dam Square
The dam, Also known as the City built on trees: Due to the soil in Amsterdam consisting of a thick layer of fen and clay, some buildings in the city are built on wooden poles that are fixed in a sandy layer that is approximately 11 meters deep. Since the old days, the houses in Amsterdam were known to have been built on wooden foundation piles that are driven deep into the clay, peat, and water until they reach the first layer of solid sand.
