Castell de Calonge is a substantial medieval fortress on the Costa Brava documented from 1019, featuring an interior courtyard surrounded by 13th-century crenellated walls and an 11th-century tower. Strategically perched on a hill overlooking the Mediterranean, the castle's complex ownership history includes periods under the counts of Girona, the monastery of Sant Feliu de Guíxols, and the Crown of Aragon. Heavily damaged by fire in 1485, it was reconstructed with a 16th-century residential palace, representing one of the region's most significant surviving castles. The well-preserved stone structures, towers, and medieval architectural elements provide commanding panoramic views of the Costa Brava landscape and coastline.
