The Roman city of Cáparra is located in the valley of the River Alagón. In Roman times it was in the province of Lusitania within the Conventus Iuridicus Emeritensis, whose capital was Colonia Augusta Emerita (modern day Mérida). It was approached via the Roman road known as the Vía de la Plata and is now permanently abandoned.
Its excellent location led to Roman settlement achieving the category of municipium under Vespasian, around the year AD 74. From that point on, Cáparra really began to develop as a city. Its decline took place during the High Middle Ages, when it began to lose its population, becoming even more depopulated after the Moorish invasion.
The most representative element of this ancient Roman city is its tetrapylon or quadrifons arch, i.e. a four-gate arch. This arch was found in the centre of the city, crossed by the Roman Silver Route.
The tetrapylon arch has large ashlar foundations with a dressed stone finish, while the capitals finish in a cornice supporting an archivolt that in turn supports the groin vault. This arch is the only one of its kind in the Iberian Peninsula.
The Roman bridge of Cáparra is part of the monumental site of Cáparra. The work is not established in time and consists of four arches, of which only the central two can be considered fully Roman.
The arches are rounded and the vaults come out from a projecting course. Upriver, one of the cutwaters of the piles in the river’s course is triangular and the other trapezoidal, while the downstream face is flat. The work is clad in granite masonry arranged in somewhat irregular rows.
References:Saint-Georges de Boscherville Abbey is a former Benedictine abbey. It was founded in about 1113 by Guillaume de Tancarville on the site of an earlier establishment of secular canons and settled by monks from the Abbey of Saint-Evroul. The abbey church made of Caumont stone was erected from 1113 to 1140. The Norman builders aimed to have very well-lit naves and they did this by means of tall, large windows, initially made possible by a wooden ceiling, which prevented uplift, although this was replaced by a Gothic vault in the 13th century. The chapter room was built after the abbey church and dates from the last quarter of the 12th century.
The arrival of the Maurist monks in 1659, after the disasters of the Wars of Religion, helped to get the abbey back on a firmer spiritual, architectural and economic footing. They erected a large monastic building one wing of which fitted tightly around the chapter house (which was otherwise left as it was).
