The Royal fortress (the 14th century)
Some researchers place this first stone fortress in the 14th century. There are others that claim this to be a 15th century fortress. This first fortress had an ellipsoidal shape, with pointed, northern and southern extremities. The walls are up to 2 m wide. They were built with dolomite limestone and pebble stone, directly on the native rock. Researches performed before the First World War show that in the northern part of the ellipse was a triangular tower with two rooms of triangular and trapezoidal shape, with analogies in the 13th to 14th centuries France and Germany.
