Castell de Gelida is a medieval fortress in Catalonia with over a thousand years of documented history, standing as one of the largest castles of medieval Catalonia. Originally built around the 10th century with possible Arab origins, it served as a strategic stronghold for Barcelona county and later became the center of the Barony of Gelida. Today, the castle features an Interpretation Centre offering guided tours, educational programs, and cultural activities including wine tourism routes and modernist tours. Visitors can explore the restored church murals and learn about the site's rich heritage through specialized programs for schools and leisure groups.
