Castell d'Argelaguer is a 15th-century fortress in Argelaguer, La Garrotxa, showcasing distinctive Catalan Gothic military architecture. The quadrangular structure features a notable western façade with Gothic windows, three stone shields (including the Montpalau family crest), and an ornate arched doorway. Historically, the Montpalau family relocated here from a nearby fortress and served as lords of Argelaguer until the mid-17th century, significantly shaping the town's development. The castle stands on Carrer de la Muralla and is now part of La Garrotxa's cultural heritage inventory, offering visitors insight into medieval Catalan nobility and Gothic design.
