MacLellan's Castle in the town of Kirkcudbright, in Galloway, was built in the late 16th century. It stands in the centre of Kirkcudbright, on the south side of the River Dee which flows into the Solway Firth. The L-plan castle was the residence of the MacLellan family from whom it derived its name. The family sold the castle in 1752, and from 1782 to 1912 it was held by the Earls of Selkirk. Today, the site is in the care of Historic Environment Scotland.
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.
