Recently Discovered Remains of a Roman Bridge in the River Trent

Abstract

The early Donjon at Langeais is among the best-known early medieval buildings in Europe, but has not been systematically studied; this paper is based on a stone-by-stone record and archaeological analysis of the standing building, and presents an interpretation of its structural and functional history. Three major structural phases have been identified. Most of what remains is original (Phase I); the ruin can be reconstructed as a main block of two floors with two tower-like attachments to the east side, probably linked by a gallery. A date of c. 1000 is proposed, but does not allow definite attribution to Fulk Nerra. Considerations of comfort and convenience were more important to the original design than security, although the building had some defensive capacity, and could have been incorporated in a walled circuit; it may have been an entire residence of a type ancestral to the mature multi-storeyed residential donjon, or have been included in an assemblage of low-level buildings, representing an alternative form of domestic planning. In the later 11th or early 12th century (Phase II), the annexes were reduced and the building deprived of any defensive character by the insertion of ground-floor doorways. The 15th century saw the demolition of the west wall, followed by consolidation of the remains, and other modifications (Phases IIIa, IIIb and IIIc). A combination of archaeological observation, recording, remote sensing and historical research shows that the fortified area extended at least to c.200 m west of the donjon in the 11th century, and contained a collegiate chapel.
