Dounreay Castle dates from the late 16th century, and is one of the few remaining examples of a Scottish Laird’s castle from that period. William Sinclair of Dunbeath, descended from a younger brother of John Sinclair, third Earl of Caithness, built the castle in the 1560s. It was damaged in 1651 by Oliver Cromwell’s New Model Army during their Scottish campaign. Now entirely ruined, the castle was still inhabited in 1863, but had become roofless and derelict by 1889.
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.
