Ballymote Castle is a large rectangular keepless castle, built around 1300. It is located in the townland of Carrownanty on the outskirts of Ballymote. It is the last of the Norman castles in Connacht. It was probably built in order to protect the newly won possessions of Richard Óg de Burgh, 2nd Earl of Ulster (also known as the Red Earl), in County Sligo, some distance from an earlier motte.
Ballymote castle is a large enclosure castle, the most symmetrical of all the Irish 'keepless' castles. It has many similarities with Beaumaris Castle, in Anglesey, Wales, built by King Edward I of England. The entrance, with a double towered gate, is in the north wall and had twin D-shaped towers. It has a gatehouse typical of the period, the outer portions of which have almost completely disappeared. The castle, however, remains an impressive structure. The interior measures about 30 square metres. There are three-quarter round towers at all four corners and also in the middle of the east and west walls. A postern gate, which was planned for the centre of the south wall, was never completed, probably because of the events of 1317, when the castle was lost to the O'Connors. A small square tower had protected this gate.
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.
