The so called castle of Aguas Mansas is a remarkable medieval castle, which is in an excellent state of conservation, located in the municipality of Agoncillo in La Rioja, Spain. It was built during the 13th and 14th centuries.
The coat of arms of the House Medrano with the Calatrava Cross can be found of the eastern facade, sign of its Dominion and its most recent historical ownership.
The monument complex is right now occupied by the Town hall, Library and other Agoncillo Town Departments and can be visited -always after booking the aforementioned dependencies- on working days during the opening hours of the administration.
