The Basilica of Saint Denis is a large medieval abbey church in a northern suburb of Paris. The building is of unique importance historically and architecturally, as its choir completed in 1144 is considered to be the first Gothic church. The site originated as a Gallo-Roman cemetery in late Roman times. The archeological remains still lie beneath the cathedral; the people buried there seem to have had a faith that was a mix of Christian and pre-Christian beliefs and practices. Around 475 St. Genevieve purchased some land and built Saint-Denys de la Chapelle. In 636 on the orders of Dagobert I the relics of Saint Denis, a patron saint of France, were reinterred in the basilica.
The basilica became a place of pilgrimage and the burial place of the French kings, with nearly every king from the 10th to the 18th centuries being buried there, as well as many from previous centuries. Saint-Denis soon became the abbey church of a growing monastic complex.
In the 12th century the Abbot Suger rebuilt portions of the abbey church using innovative structural and decorative features. In doing so, he is said to have created the first truly Gothic building. Before the term 'Gothic' came into common use, it was known as the 'French Style' (Opus Francigenum). The basilica"s 13th-century nave is also the prototype for the Rayonnant Gothic style, and provided an architectural model for cathedrals and abbeys of northern France, England and other countries.
As it now stands, the church is a large cruciform building of 'basilica' form; that is, it has a central nave with lower aisles and clerestory windows. It has an additional aisle on the northern side formed of a row of chapels. The west front has three portals, a rose window and one tower, on the southern side. The eastern end, which is built over a crypt, is apsidal, surrounded by an ambulatory and a chevet of nine radiating chapels. The basilica retains stained glass of many periods (although most of the panels from Suger"s time have been removed for long-term conservation and replaced with photographic transparencies), including exceptional modern glass, and a set of twelve misericords.References:
The Arch of Constantine is situated between the Colosseum and the Palatine Hill. It was erected by the Roman Senate to commemorate Constantine I's victory over Maxentius at the Battle of Milvian Bridge in 312. Dedicated in 315, it is the largest Roman triumphal arch. The arch spans the Via triumphalis, the way taken by the emperors when they entered the city in triumph.
Though dedicated to Constantine, much of the decorative material incorporated earlier work from the time of the emperors Trajan (98-117), Hadrian (117-138) and Marcus Aurelius (161-180), and is thus a collage. The last of the existing triumphal arches in Rome, it is also the only one to make extensive use of spolia, reusing several major reliefs from 2nd century imperial monuments, which give a striking and famous stylistic contrast to the sculpture newly created for the arch.
The arch is 21 m high, 25.9 m wide and 7.4 m deep. Above the archways is placed the attic, composed of brickwork reveted (faced) with marble. A staircase within the arch is entered from a door at some height from the ground, on the west side, facing the Palatine Hill. The general design with a main part structured by detached columns and an attic with the main inscription above is modelled after the example of the Arch of Septimius Severus on the Roman Forum.
