Castle of Castelo Bom, Medieval castle in Almeida, Portugal.
The Castle of Castelo Bom sits on a rocky hilltop near the Côa River with uneven walls and a square keep showing seven narrow defensive openings. The site preserves sections of walls, a town gate, and a partially standing tower that are protected as a National Monument.
The castle was founded in the 12th century and transferred to Portuguese control in 1296 when King Denis took the region through a border agreement. This marked a key moment when Portugal established its northern frontier.
The castle shows how medieval people built with local granite and positioned narrow openings in the walls for defense. Walking through the remains, you can see how the structure once controlled the valley below and protected the settlement.
The ruins are open year-round, though paths leading up can be steep and uneven, especially after wet weather. Sturdy shoes and some time for the climb help you explore the walls and towers comfortably.
Hidden beneath the fortress remains is an old medieval water tank that collected rainwater for the castle. Later, two wells from the 16th century were dug to bring water to the entire village living below.
