We are possibly before the most important monument of the whole Visigothic period. With a cruciform plan, with three naves and only one apse, includes the lateral compartments in its original design that we consider were added later. It has also a magnificent sculpted decoration.

El monasterio de Santa María de Moreruela fue trasladado de Moreruela de Suso a su actual enclave en 1143 en época de Alfonso VIII. Es considerado por muchos como el primer enclave del Císter en nuestro país y fue declarado Monumento Nacional en 1831. Posee una cabecera monumental que afortunadamente aún se conserva compuesta de siete absidiolos en disposición radial en torno a la girola que rodea el majestuoso altar central.

Situado en el Valle del Silencio se encuentra este monasterio construido a principios del siglo X por San Genadio. Es una iglesia de una sola nave, dividida en dos tramos, con dos pequeñas como naves de crucero adosadas a la primera y con dos ábsides contrapuestos. Toda ella es abovedada, de forma que cada uno de los seis módulos que la forman dispone de un tipo distinto de bóveda excepto los dos de crucero, que debían ser iguales.

This small church is located at the entrance of Ponferrada. It has a single nave with a magnificent oval apse that consists of nine horseshoe arches attached to the wall, upon columns and capitals with access through a triumphal arch, also horseshoe, covered with a magnificent groin vault of eleven edges that lean upon the centre of each arch dividing it in other eleven segments of clear Cordovan descent.

Built around 910, its structure seems a compendium of the most remarkable characteristics of Spanish pre Romanesque architecture that has reached these days. In fact, it is a church with three naves, three apses, being the central one semi circular, and squre the lateral ones, with nave and crossing lantern and another apse at the end of the central nave. All of that supported upon horseshoe arches

Located where Wamba was anointed king, it was built in the first half of the 10th century upon the remains of a Visigothic church, of which fragments of the decoration have been preserved. From the Mozarabic period, only the chevet has been preserved, with three apses covered with a horseshoe vault, the continuation of magnificent access arches, the last two sections of the naves and the northern wall; the rest corresponds to a reconstruction in the 12th century.
