The Catedral de Santiago Foundation was established in 2008 to promote, support, and publicize Santiago de Compostela Cathedral, its surroundings, and its artistic and cultural heritage, as well as to manage and run the infrastructures to support that.

The Santiago Cathedral Museum allows visitors to find out more about the cathedral's history and art by exploring its many spaces and temporary exhibitions: a journey through the cathedral's history and art, through its finest artistic pieces.
