Castell de Molinàs rises in a secluded valley west of Colera on Costa Brava, serving as a medieval coastal defense tower protecting the nearby Sant Quirze Abbey. Dating to the 12th or 13th centuries, this Romanesque structure was built strategically atop earlier fortifications to maximize defensive capabilities. The castle's ruined rectangular tower stands approximately ten meters high, featuring three rows of loopholes and a well-preserved machicolation for overhead defense. Today the site remains partially excavated and protected as a cultural asset of local interest, accessible through forest paths that lead to the historic Sant Miquel church, offering insights into medieval maritime security infrastructure.
