Castro de Mallou is an archaeological hillfort dating from the 6th century BC to the 1st century AD, now part of the Carnota Open-air Archaeological Museum in Galicia. The site features an oval structure protected by two main walls and a third reinforcing wall on the southern side, covering approximately 1.38 hectares with an inner enclosure of around 4,450 square meters. Located just north of Moor's Tower and accessible through the village of Mallou, the site sits at 116 meters elevation surrounded by scrub brush and pines. According to local legend, this was the residence of Queen Lupa, whose throne—a distinctly carved stone—remains preserved in the site's center, representing an important example of Castro culture settlement patterns in Galicia.
