Besieged in 778 by Charlemagne, Château Fort de Lourdes became the residence of the Counts of Bigorre in the 11th and 12th centuries. In the 13th century, it passed into the possession of the Counts of Champagne, part of the kingdom of Navarre before coming under the crown of France under Philippe le Bel. It was ceded to the English by the Treaty of Brétigny in 1360, before returning to France at the start of the 15th century after two sieges. In the 17th century, the castle became a royal prison, and a state prison after the French Revolution, continuing in this role until the start of the 20th century when it became the Pyrenean Museum (1921) which it remains.
The castle's origins go back to Roman times. Various remains from this era (fragments of sculpture, votive offerings, wall foundations) were brought to light by military engineering work in the 19th century. However, a consequence of these works was the destruction of the greater part of the ancient walls. The finds are exhibited on the site.
Today, the oldest remains date from the 11th and 12th centuries and consist of the foundations of the present fortifications. The castle was reinforced in the 13th and 14th centuries (construction of the keep), and again in the 17th and 18th centuries.
The Notre-Dame-du-Château chapel houses the furniture of the former parish church of Saint-Pierre de Lourdes, destroyed in 1904. The present chapel is constructed with recycled material from Saint-Pierre de Lourdes.
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.
