Skipness Castle was built in the early 13th century by the Clan MacSween with later fortifications and other additions made to the castle through the 13th, 14th and 16th centuries. The castle was garrisoned with royal troops in 1494 during King James IV of Scotland's suppression of the Isles. Archibald Campbell, 2nd Earl of Argyll granted Skipness to his younger son Archibald Campbell in 1511.
During the Wars of the Three Kingdoms in 1646, the castle was besieged by forces under the command of Alasdair Mac Colla. During the siege, Alasdair's brother, Gilleasbuig Mac Colla, was killed in August 1646. The castle was abandoned in the 17th century. The Green Lady of Skipness Castle is said to haunt the location.
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.
