Horncastle Castle has been described as a probable Fortified Manor House.

There are masonry ruins/remnants remains.

This site is a scheduled monument protected by law.
This is a Grade 1 listed building protected by law*.


The castle was said to have been demolished in a charter of 1146 (Dugdale, Baronage I, 39; Registrum Antiquissimum of Lincoln I, p. 287.) This may be an error for Thorngate (in the same hands), but considerable remains of the Roman wall still survive there. ( Arch. Jl. CXII, pp. 38-9). (Renn)

King writes Roman only.

Horncastle is a river crossing, and was a major Saxon town, with a mint. The manor house is within the Roman fortified town. The strength of the C3 walls in C12 is debatable, but they were still up to 4yds high in the early C18. There must be a possibility of some form of C11 or C12 defensive structure here based on the Roman walls. It is clear that the 'castel' mentioned by Leland was the Roman town but Camden was writing about structure being razed in the C12. Is it possible that the Roman walls were in such good condition that they needed no improvement in the medieval period and there are therefore no obvious medieval defensive works? The Bishop of Carlisle had a residential manor here, although only from the C13. This manor house was in the north-west corner of the circuit of the Roman wall. Horncastle was held by the de Condet family in the C12 who certainly had a residence here, probably in the same place. Given their baronial status it is entirely possible their manor house was defensible, although there is nothing to suggest it was isolated from the rest of the town by either a stone wall or significant earthworks.

Minor archaeological investigations, such as watching brief reports, and some other 'grey' literature is most likely to be held by H.E.R.s but is often poorly referenced and is unlikely to be recorded here, or elsewhere, but some suggestions can be found here.
The possible site or monument is represented on maps as a point location. This is a guide only. It should be noted that OS grid references defines an area, not a point location. In practice this means the actual center of the site or monument may often, but not always, be to the North East of the point shown. Locations derived from OS grid references and from latitude longitiude may differ by a small distance.
