The Broch of Burrian is an Iron Age structure, which stands on a small headland next to a rocky shoreline. It is separated from the hinterland by a series of defensive earthworks.
The broch has an external diameter of 18 metres and an internal diameter of 9.5 metres. The entrance passage is on the southeast side, and the walls are solid. There is a small room in the inner wall of the broch on the northeast side. The broch is surrounded by outer defences consisting of the remains of four concentric ramparts on the landward side.
The Broch of Burrian was excavated by William Traill, proprietor of the island, in 1870 and 1871. A large number of artefacts, including a significant quantity of worked bone objects, were discovered. In addition, a number of artefacts of early historic or Pictish date were found. These include a cross-slab with ogham inscription, painted pebbles and part of an iron bell of Celtic type. Part of a Pictish house was uncovered to the north east side of the broch. The finds are now in the National Museum of Scotland.
The evidence suggests two phases of occupation, both dating to the Iron Age. In the second phase, the broch was converted into a sort of wheelhouse. The second phase went on for a long time, as there were clear Pictish elements among the finds, from as late as the 7th to the 9th centuries AD. Two items (the cross-slab and the iron bell) suggest early Christian activity, although there is as yet no other evidence for monastic settlement.References:
The Odeon of Herodes Atticus is a stone theatre structure located on the southwest slope of the Acropolis of Athens. It was built in 161 AD by the Athenian magnate Herodes Atticus in memory of his wife, Aspasia Annia Regilla. It was originally a steep-sloped theater with a three-story stone front wall and a wooden roof made of expensive cedar of Lebanon timber. It was used as a venue for music concerts with a capacity of 5,000. It lasted intact until it was destroyed and left in ruins by the Heruli in 267 AD.
The audience stands and the orchestra (stage) were restored using Pentelic marble in the 1950s. Since then it has been the main venue of the Athens Festival, which runs from May through October each year, featuring a variety of acclaimed Greek as well as International performances.
