Sketrick Castle castle dates from the late 12th century. In the 14th century it was acquired by Sir Robert Savage. The Annals of the Four Masters record the capture of the castle in 1470 by an army led by the O'Neill to assist the MacQuillans. They took the castle and it was given to MacQuillan for safe keeping. It was intact until 1896 when a storm demolished much of it.
Sketrick Castle was four storeys high, with a boat bay and a stone subterranean passage discovered in 1957. It had four chambers at ground level, the largest with a vault constructed on wicker centring, as well as two brick-lined recesses, probably ovens. It has lintels running under the bawn wall to a chamber with a corbel over a fresh water spring. Parts of the bawn wall still survive to the north and east of the castle.
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.
