The Fundación Castillo de la Estrella in Montiel is a heritage preservation organization dedicated to the restoration and study of a medieval castle. Established following the castle's recovery in 2012, the foundation manages comprehensive restoration efforts through community collaboration, employment programs, and archaeological research. The organization operates a virtual museum, hosts educational events, and organizes conferences focused on medieval construction history. The castle itself holds significant regional medieval importance, and the foundation's work emphasizes both physical restoration and public engagement to preserve this historic site for future generations.
