Amboise Castle at Loire river

The Amboise Castle (Château d`Amboise) was built over the Loire in the place where it is divided into two branches, with the island of Saint-Jean in the middle. In that place on the Loire there was a ford and a very important crossing. In 10 century the powerful House of Amboise decided to build a strong fortress to control this crossing. The crossing was built as a continuation of the rocky overhang above the river.
