The Atalaya Castle in Villena, province of Alicante, commands the former frontier between Castile and Kingdom of Aragon.
The fortress was built in an unknown age, although not after the 12th century, since Arab sources mention it in 1172. It has been speculated that the fortification could have been built over a Roman castrum or villa, but no proof of this has been found.
The fortress was an important stronghold on the northern frontier of the Islamic emirate of Iberia. It resisted three different sieges laid by James I of Aragon until finally conquered in 1240.
In 1476 the citizens of Villena, encouraged by the Catholic Monarchs, rebelled against the marquesses. After this event, the castle stopped to be residence of the marquisses, and, together with the city, became a royal possession.
During the Revolt of the Brotherhoods (1519–1523), viceroy Diego Mendoza took refuge in the fortress after his defeat at Gandía, and from here set out the troops which restored the royal power in Spain. During the War of Spanish Succession (1701–1713), 50 Bourbon loyalist troops sustained a siege of 8 days from the biggest part of the Austrian army. The castle was abandoned after the loot perpetrated by the French Marshal Suchet in the course of the Peninsular War (early 19th century). A first restoration was carried out in 1958. The castle is now in good conditions.
Across the upper part of the external wall is a chemin-de-ronde connecting all the towers. Within the inner gate remains have been excavated, which are thought to belong to Sanctuary of the Virgin of the Snow, whose existence was known from written documents.
The fortress has a concentric plan, with an inner and higher line of walls forming a square, and with a rectangular barbican forming a larger inner space in front of the keep. The inner square polygonal in plan, with round towers at the corners, aside from one which is occupied by the keep. These walls were built in the Almohad era, and were covered in the 15th century by order of Don Juan Pacheco. Over this sector is another path leading to the keep. The latter and the towers have rectangular merlons.
The keep is quite higher than the other fortifications. Its lower sections were built in Almohad times using the rammed earth technique. The small entrance leads to a 7x7 m hall, whose walls have an average thickness of 3.5 m, and which is covered by an Almohad ceiling from the 12th century.
The stairs leading to the upper sections house a reproduction of a graffitied khamsa, the original being in Villena's Museum. The mid hall has also an Almohad ceiling. The two upper sections were built in the mid-15th century.
References:Herceg Novi was founded (on a former small fishing village, existing since Roman Empire times) as a fortress in 1382 by first Bosnian King Stjepan Tvrtko I and was called Sveti Stefan or Castelnuovo. The Turks conquered Herceg Novi in 1482, and ruled for 200 years, until 1687. However, there was a short pause between 1538 and 1539 when it was held by the Spaniards before they were defeated in the Siege of Castelnuovo. Turkey ruled again until 1687, from then until 1797, the town was ruled by the Venetian Republic.
The Herceg Novi old town is amazing. It is on a fairly steep hill that leads all the way down to the sea. Wandering through the small stairways to the various plazas and fortresses is a many hour adventure.
