Burroughston Broch is an Iron Age structure located on the island of Shapinsay. Excavated in the mid 19th century, Burroughston Broch is still well-preserved. The drystone walls are up to four metres thick in some parts and there is a complete chamber intact off the entrance passage. Some remains of stone fittings are evident in the interior.
The walls of Burroughston Broch have an external diameter of around 18 metres, and an internal diameter of around 10 metres. From the outside, the building appears as a grassy mound, and little of the outer wall is exposed.
The entrance passage is on the east side, and is about 4 metres long, 1.2 metres wide and 1.8 metres high. There is an elongated guard room opening from the left side of the passage. Inside the broch, the outer face of the upper gallery is still visible, and traces of an opening to the upper gallery are still apparent. A deep well is present in the broch floor: the upper part being dry stone masonry, the lower being cut into the rock.
In the sloping area in front of the broch entrance are traces of 'out-buildings' now covered with turf. A wall, ditch and rampart, which probably once encircled the broch, are still evident around the structure.
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.
