PR3-Van de Basiliek naar het park Georges-Valbon

The Basilica of Saint Denis (French: Basilique royale de Saint-Denis, or simply Basilique Saint-Denis) is a large medieval abbey church in the city of Saint-Denis, now a northern suburb of Paris. The building is of unique importance historically and architecturally as its choir, completed in 1144, shows the first use of all of the elements of Gothic architecture. 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 relics of St-Denis, which had been transferred to the parish church of the town in 1795, were brought back again to the abbey in 1819. 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. (It was not used for the coronations of kings, that function being reserved for the Cathedral of Reims; however, French Queens were commonly crowned there.) "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.[3] The basilica's 13th-century nave is the prototype for the Rayonnant Gothic style, and provided an architectural model for many medieval cathedrals and abbeys of northern France, Germany, England and a great many other countries. The abbey church became a cathedral in 1966 and is the seat of the Bishop of Saint-Denis. Although known as the "Basilica of St Denis", the cathedral has not been granted the title of Minor Basilica by the Vatican. From : en.wikipedia.org/wiki/basilica_of_st_denis

La Vieille Mer est une petite rivière, progressivement busée, qui prend sa source à Dugny, passe dans le parc Départemental Georges-Valbon et s'écoule sur 6 km vers Saint-Denis ou elle se jette dans la Seine.

Georges Valbon Country Park covers acres of open space, which is managed for the benefit of outdoor-life for the community and visitors. The site was formerly once part of the prairie of France. This park in La Courneuve is known now as the largest man-made park since the era of Napoleon III. However, its essential integrity was saved from urbanization through the persevering land key-policy actors. Their aim was to manage and protect this open-space area and its wildlife for the benefit of the public in an urban environment.
