Gilbertfield Castle is within the former barony of Drumsagard, which was a possession of the Hamiltons. The castle was built in the early 17th century, and the date 1607 is displayed on a heraldic panel above the door. The castle was later lived in, around the turn of the 18th century, by William Hamilton of Gilbertfield (1665-1751), a retired soldier and writer.
Gilbertfield is a well-planned L-plan tower house. The stair tower, which projects to the north, was large enough to accommodate a series of rooms as well as a square turnpike stair.
The basement level was vaulted, and contained cellars and a kitchen, which had a large fireplace and oven. A service stair connected the basement with the hall above. The hall itself had a smaller fireplace, as well as large windows with gunloops in between. Above the hall were two further floors, each with three rooms; two in the main block, and one in the wing. At the highest level, the garret, two round turrets projected at the south-east and north-west corners. There was no parapet.
The castle is now a neglected ruin, the east wall having collapsed in the 1950s. Only the corbelling of the north-west turret remains.which fell down in the late 1960s. It is now deemed extremely dangerous as a lot of the brick work has fallen each year. The turret fell in the 1970s.
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.
