The Tirana Mosaic is believed to have been part of a 3rd century Roman house, referred to by local archeologists as the 'Villa rustica'. Later, in the 5th and 6th centuries, a Paleo-Christian Basilica was built around this site.
The ruins of this Paleo-Christian Basilica were discovered in 1972. In 2002, some other objects were found around the ruins of the house, and today they form the Archaeological Complex of the Mosaic of Tirana. It is the only archaeological monument within the city. Some of the ancient mosaics discovered at the site that feature diverse geometrical patterns and depict poultry and fish.
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.
