At 955m above sea level, Buffavento castle stands the highest of the three crusader castles in Cyprus. It probably originated as a Byzantine watch tower to guard against Arab raiders in the 10th century. The castle was extended during the Lusignan rule (1192–1489). The Lusignan kings used the castle mainly as a political prison. In particular, Peter I when reluctantly warned by his friend John Visconti of the queen's infidelity, repaid the favour by imprisoning and torturing him at Kyrenia, and later locking Visconti up at Buffavento to starve to death. By the 16th century, the castle was dismantled by the Venetians in an attempt to protect themselves, as their focus moved to the strongholds along the coast at Kyrenia and Famagusta.
From the seaward side, the castle is almost invisible, and the best long distance view is from the Nicosia side, where you can clearly see the remains of the castle bulging out from the top of the mountain. On the top level there are remains of a few buildings and a ruined chapel. However, the climb is worth it for the views alone, taking in Kyrenia, Famagusta, Nicosia and, on a good day, the Troodos Mountains.
References:The ancient Argos Theater was built in 320 BC. and is located in Argos, Greece against Larissa Hill. Nearby from this site is Agora, Roman Odeon, and the Baths of Argos. The theater is one of the largest architectural developments in Greece and was renovated in ca 120 AD.
The Hellenistic theater at Argos is cut into the hillside of the Larisa, with 90 steps up a steep incline, forming a narrow rectilinear cavea. Among the largest theaters in Greece, it held about 20,000 spectators and is divided by two landings into three horizontal sections. Staircases further divide the cavea into four cunei, corresponding to the tribes of Argos A high wall was erected to prevent unauthorized access into the theatron and may have helped the acoustics, but it is said the sound quality is still very good today.
Around 120 CE, both theaters were renovated in the Roman style.
