Largo di Torre Argentina is a square that hosts four Republican Roman temples, and the remains of Pompey's Theatre. The name of the square comes from the Torre Argentina, which takes its name from the city of Strasbourg, whose Latin name was Argentoratum.
The four temples, originally designated by the letters A, B, C, and D, front onto a paved street, which was reconstructed in the imperial era, after the fire of AD 80. The area was delineated to the north by the Hecatostylum (one-hundred columns porch) and the Baths of Agrippa, and to the south by the buildings related to the Circus Flaminius, to the east by the great porched square of Porticus Minucia Frumentaria, and to the west by the Theatre of Pompey.
Julius Caesar was killed in the Curia of the Theatre of Pompey, and the spot he was believed to be assassinated is in the square.
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.
