Glengarnock Castle is one of the ancient ruined fortifications of Ayrshire. Its keep is located on a remote rocky promontory overlooking the River Garnock about 2 miles north of the town of Kilbirnie in North Ayrshire. There is no clear account of when this was erected or by whom, but it may have been built by the Cunningham (or Cunninghame) family or by the Riddels who preceded them.
In the 12th and 13th centuries, the lands here were held for the King by the De Morville family, hereditary Great Constables of Scotland. A castle may have been built here by them; a convenient site in relation to the abbey they founded at Kilwinning. The Barony of Glengarnock then passed to the Riddels and the Cunninghames. The Cunninghames retained the castle until the early 17th century and by the 18th century it had been abandoned. The Honourable Patrick Lindsay of Kilbirnie Place purchased the castle and estate of Glengarnock in 1677 from Richard Cuninghame, the last of the Cuninghames of Garnock. In 1707 both baronies were united in the Barony of Kilbirnie, with Kilbirnie Place as the principal dwelling.
The castle is an example of a keep with courtyard attached and dates from the period 1400-1542, with various later buildings in the courtyard.
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.
