The Basel Minster is one of the main landmarks and tourist attractions of the Swiss city of Basel. It adds definition to the cityscape with its red sandstone architecture and coloured roof tiles, its two slim towers and the cross-shaped intersection of the main roof.
The hill on which the Minster is located today was already a building site in the late Celtic Era in first century BC. A pre-Roman rampart (Murus Gallicus) was uncovered during archeological excavations. The first bishop of Basel is claimed to be Justinianus 343-346 AD. The bishop's see was relocated from Augusta Raurica (today Kaiseraugst) to Minster hill during the Early Middle Ages. This transfer presumably took place at the beginning of the 7th century under bishop Ragnacharius, a former monk of monastery Luxeuil. There is no historical evidence for the existence of a cathedral before the 9th century.
Some time after the turn of the first millennium a new building was built in the early Romanesque style of the Ottonian period was built by order of Bishop Adalberto II (approx. 999 - 1025). The crypt of this building, consecrated in 1019, had not been expanded. At the end of the 11th century a tower made of light-colored limestone and molasse was erected on the western side of the building. This historic structure remains forming the bottom part of the north tower (Georgsturm) today.
The building as it stands today dates back for the most part to the late Romanesque building constructed in the last third of the 12th century and completed around 1225. On the foundations of the previous buildings a church with three naves and a transept was built. The western facade was finished sometime in the latter part of the 13th century. A third storey was added to Georgsturm, and the Martinsturm was started.
Even though supported by massive pillars, an earthquake in 1356 destroyed five towers, the choir and various vaults. Johannes von Gmünd, who was also the architect of Freiburg Minster, rebuilt the damaged cathedral and in 1363 the main altar was consecrated. In 1421 Ulrich von Ensingen, who constructed the towers of the minsters in Ulm and Strasbourg, began the extension of the northern tower. This phase ended in 1429. The southern tower was completed by Hans von Nussdorf in 1500. This date marks the official architectural completion of the minster. In the 15th century the major and the minor cloisters were added. The minster served as a bishop’s see until 1529 during the Reformation.
From 1852 until 1857 the rood screen was moved and the crypt on the western side was closed. In the 20th century the main aim of renovations has been to emphasize the late Romanesque architecture and to reverse some modifications made in the 1850s. Additionally, the floor was returned to its original level in 1975 and the crypt reopened. A workshop dedicated to taking care of the increasingly deteriorating sandstone exterior was set up in 1985.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.
