Originally the Doornenburg castle was a fortified manor built in the 9th century, under the name Villa Dorenburc. In the 13th century it was converted into a modest castle. Through the centuries the castle was expanded further into the current form. The front-castle was built in the 15th century. The front-castle contains sleeping quarters, a chapeland a farm, the last being a unique feature for a Dutch castle. It is one of the biggest and best preserved castles in the Netherlands.
Castle Doornenburg was occupied until the 19th century. After that it fell into neglect. In 1936 the Stichting tot Behoud van den Doornenburg was created, which had the castle restored from 1937 to 1941. In the end of the Second World War the castle was almost completely destroyed. It was long thought the Germans had blown it up, but it turned out that the castle had been hit by a British bombardment in March 1945. The castle was completely rebuilt from 1947 to 1968.References:
The two-tiered Roman amphitheatre is probably the most prominent tourist attraction in the city of Arles, which thrived in Roman times. Built in 90 AD, the amphitheatre was capable of seating over 20,000 spectators, and was built to provide entertainment in the form of chariot races and bloody hand-to-hand battles. Today, it draws large crowds for bullfighting as well as plays and concerts in summer.
The building measures 136 m in length and 109 m wide, and features 120 arches. It has an oval arena surrounded by terraces, arcades on two levels (60 in all), bleachers, a system of galleries, drainage system in many corridors of access and staircases for a quick exit from the crowd. It was obviously inspired by the Colosseum in Rome (in 72-80), being built slightly later (in 90).
With the fall of the Empire in the 5th century, the amphitheatre became a shelter for the population and was transformed into a fortress with four towers (the southern tower is not restored). The structure encircled more than 200 houses, becoming a real town, with its public square built in the centre of the arena and two chapels, one in the centre of the building, and another one at the base of the west tower.
This new residential role continued until the late 18th century, and in 1825 through the initiative of the writer Prosper Mérimée, the change to national historical monument began. In 1826, expropriation began of the houses built within the building, which ended by 1830 when the first event was organized in the arena - a race of the bulls to celebrate the taking of Algiers.
Arles Amphitheatre is listed as a UNESCO World Heritage Site, together with other Roman buildings of the city, as part of the Arles, Roman and Romanesque Monuments group.
