Royal Fortress of the Conception

The fortress of Real Fuerte de la Concepción (English: Royal Fortress of the Conception) is a star fortress built in the Vaubanesque style. It is located 0.6 miles (0.97 km) west of the village of Aldea del Obispo in the province of Salamanca, western Spain, part of the autonomous community of Castile and León.

The fortress was constructed there because of its position of great strategic significance due to its proximity to the border between Spain and Portugal which lies 0.4 miles (0.64 km) to the west of the fortress. The Fortress of the Concepcion is also opposite the Portuguese castle fortress of Almeida which lies 5.5 miles (8.9 km) west-north-west of the fortress.

In 2006, the derelict fortress was sold privately and the site was renovated into a luxury hotel which opened in 2012.
