The Cathedral Museum consists of three different areas, one being the crypt below the Porch of Glory, where its building is explained. A chapel houses the tombs of the monarchs of Galacia, whilst silver and gold pieces are kept in the Treasury. In the cloister area, several rooms have displays about the cathedral`s history and development. There are also collections of paintings and tapestries, and some of the cloths date back to the 13th Century.
