Macenas castle or watchtower is an 18th century military structure built to keep watch the coast. In 1849 it was occupied by the carabineros and after the war arrived the Civil Guard and was built an access to the castle. It was restored in the 1990’s.
On its southern side there is a dirt track which leads to the La Torre del Perulico, or Torre del Peñon tower, built during the Nasrid period (13th-15th centuries). This tower was part of a defensive system along the Mediterranean coast. The rock, the tower and the natural arch form a uniquely beautiful whole.
References:The Gravensteen is a castle in Ghent originating from the Middle Ages. The name means 'castle of the counts' in Dutch. Arnulf I (918–965), Count of Flanders, was the first to fortify this place, building a medieval bastion on this high sand dune, naturally protected by the river Leie and its marshy banks. This bastion consisted of a central wooden building and several surrounding buildings, also in wood.
In the early 11th century, the wooden building was replaced by a stone residence, consisting of three large halls that made up three storeys, connected by a stone stairwell. The monumental stone staircase, the light openings, the fireplaces built into the walls and the latrines were signs of considerable luxury and comfort in those days. There was probably also a tower.
