After the original Benedictine Abbey on the Altmünster Plateau had been destroyed in 1542, the monks built a new abbey or Neumünster in 1606 in the Grund. This in turn was destroyed by fire in 1684 but was rebuilt on the same site in 1688 and extended in 1720. After the French revolution, it served as a police station and prison before becoming a barracks for the Prussians after Napoleon's defeat in 1815. From 1867, it once again became a state prison. During World War II, the Nazis used the Abbey to imprison political resisters to their occupation of Luxembourg. Among the most notable of those political prisoners was Luxembourg's best-known sculptor Lucien Wercollier.
Today Neumünster Abbey is a public meeting place and cultural centre. Since 1997, it has been the home of the European Institute of Cultural Routes.
References:The ancient Argos Theater was built in 320 BC. and is located in Argos, Greece against Larissa Hill. Nearby from this site is Agora, Roman Odeon, and the Baths of Argos. The theater is one of the largest architectural developments in Greece and was renovated in ca 120 AD.
The Hellenistic theater at Argos is cut into the hillside of the Larisa, with 90 steps up a steep incline, forming a narrow rectilinear cavea. Among the largest theaters in Greece, it held about 20,000 spectators and is divided by two landings into three horizontal sections. Staircases further divide the cavea into four cunei, corresponding to the tribes of Argos A high wall was erected to prevent unauthorized access into the theatron and may have helped the acoustics, but it is said the sound quality is still very good today.
Around 120 CE, both theaters were renovated in the Roman style.
