The Abbey of St. Martin, established in 1124 in Laon in northern France, was one of the earliest foundations of the Premonstratensian Order. Along with Cuissy Abbey and Floreffe Abbey it counted as one of the primarii inter pares, or senior houses, of the order.
The Premonstratensian community was founded by Barthélemy of Jur, bishop of Laon, in co-operation with Saint Norbert of Xanten, who settled it with twelve canons from Prémontré Abbey. It took over the site of an earlier college of canons regular, established in the Carolingian period, which had fallen into decay.
It was dissolved in the French Revolution. The church of St. Martin in Laon, dating from mid to late 12th century, is still in use as a parish church. The former monastic buildings were converted into a hospital in 1810.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.
