Torretrencada is a Talayotic settlement (1000-700 BCE) that was occupied until the Roman conquest in 123 BCE. Several of its monuments can still be seen. They include the talayot a seriest of artificial burial caves dug out of the rocky ground and burial chambers carved in the rock, probably dating from the high medieval period. The taula is one of the most beautiful on the island, with a reinforcement pillar at the back, but all that is left of the surrounding wall is a section underneath the modern dry-stone wall. The site dates back to the post-Talayotic period (650-123 BCE) and was used by the community for performing rituals.
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.
