We just learned about the Chillon Castle.
Another famous castle is Castillo de Colomares, in Benalmádena, Spain in 1987 by an American doctor named Dr Esteban Martín Martín.
This is actually a monument, not really a castle.
It was built to honor the discovery of the Americas by Christopher Columbus.
At a size of 1,500 square meters it is the largest monument to Christopher Columbus, but it also has a tiny church inside that is only 1.96 square meters.
It was made in a way to try and look like some of the different building and castle styles from when Columbus made his journey.
There are also parts of the monument shaped like a boat, for the trip he made across the ocean.
