Bridge

The Plougastel Bridge, or Albert-Louppe Bridge, is a bridge over the river Élorn near Brest, France, connecting Plougastel-Daoulas and Le Relecq-Kerhuon. Construction on the Plougastel Bridge started in 1926 and was completed on 9 October 1930. Part of it was destroyed by the German army in 1944, and shortly after was closed for repair. It was reopened after the widening and construction five years later. Between 1991 and 1994 another bridge, the Pont de l'Iroise, was built parallel to this bridge. Today the Plougastel carries tractor, pedestrian and bicycle traffic and is a landmark on the route of the Paris–Brest–Paris bicycle event. The Plougastel Bridge is an arch bridge, or has a fixed, double deck structure. The arches are composed of concrete and have a total length of around 888m.

Castle

The Élorn is a 56.4-kilometre (35 mi) long river in Brittany, France. Its source is in the monts d'Arrée, 1.5 kilometres (0.9 mi) north-northeast of Le Tuchenn Kador, and it then runs through several small towns such as Sizun and Landivisiau before flowing out into the roadstead of Brest. The maritime part of the river stops at Landerneau, where the Pont de Rohan blocks seaborne ships from sailing any further upstream. The river also crosses the château de la Roche-Maurice and many abandoned mills, and on the banks of its maritime part are several family properties belonging to families in Brest (Park an Coat, le Frout, Beau Repos, le Petit Manoir de Poul ar Velin). At low tide the mud is met, at high tide the sea flows over the countryside.
