Dun Telve is one of the best preserved Iron Age brochs in Scotland. The neighbouring broch of Dun Troddan lies 470 metres to the east, and the 'semi-broch' known as Dun Grugaig is around 2.5 kilometres further east.
Dun Telve is over 20m in diameter and the portion that still stands is about 10m high. Behind the narrow, west-facing entrance doorway, a 5m-long passage leads into the interior.
Along the passage is a small side-chamber, sometimes called a ‘guard cell’. The door (now missing) within the passage was well secured by a bar hole in the wall, just as in a medieval castle.
The section left standing gives a perfect cross-section to show how brochs were constructed. The two concentric drystone walls are tied together by large horizontal slabs. These slabs also form the floors of the narrow galleries between.
Access up the tower is by a winding stone stair, and openings at intervals once gave access to the upper floors. The presence of two horizontal stone ledges, or scarcements, up the height of the surviving section suggests that there were two upper floors. The top floor would have been around 9m above ground level.
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.
