The Museo de Tapices de Oncala is housed in the 18th Century Neo-classical Church of San Millan. The collection was donated by a citizen of the town and it consists of eighteen tapestries from the early 17th Century. They were commissioned for the Convento de las Desclzas in Madrid and some of them bear the mark of a tapestry weaver in Brussels. The cloths have recently been restored by various methods.
