Kilmartin Castle, a small tower house, dating from about 1580, stands above the village. Kilmartin was a property of the Campbells, many of whom are buried in the churchyard. John Carswell, Rector of Kilmartin and later titular Bishop of the Isles, lived here before moving to his new residence at Carnasserie Castle. The castle comprises an oblong, three-storey main block, with round towers to the north-east and south-west corners, as well as a small stair tower in the west front. Formerly ruined, it has been restored as a private house in recent years. Shot holes and iron yetts over the windows have been retained.
Carswell moved into Carnasserie Castle in 1565 and died in 1572, so kilmartin castle must have been built before either date.
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.
