Castle of Alandroal, Medieval castle in Alandroal, Portugal
Castelo do Alandroal is a medieval fortress built on an oval plan with three square watchtowers and a central keep. Two main gates, the Legal Gate and Arrabalde Gate, serve as the primary entrances to the complex.
The fortress was founded in 1294 under King Dinis as a defensive position on the border with Spain. Its construction came after the weakening of Moorish kingdoms and represented a new phase of fortification building in the region.
The name comes from an old Arab settlement, and Islamic building styles shaped how the towers and gates were designed. You can see this influence in the curved window openings and the way the stonework was finished.
The ruins are open for visitors to explore, though some sections are undergoing ongoing restoration work. Visit early in the day or late afternoon when fewer people are around and the light is better for seeing the stonework details.
The Arrabalde Gate holds stone markings that once served as standard measurements for local commerce and trade. These carved lines show that the fortress operated as both a military stronghold and a checking point for merchants.
