Althorp has been described as a probable Fortified Manor House.

There are no visible remains.

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


Althorp was purchased in 1508 by John Spencer, and was emparked 4 years later. It is probable that there was already a house here, as his grandson, another Sir John, built the present one. This has never been pulled down though it has been so much altered that there is nothing of that date visible except its original plan. Robert, son of the 3rd Baron and Earl of Sunderland converted Althorp into a house of the late 17th cent. and many of the rooms have not been altered since. His grandson, the 5th Earl started to build the stables, and also built the great dining room to the east. (PastScape ref. Arch. J. 1953)

A Royal licence to crenellate was granted in 1512 Nov 8 (Click on the date for details of this licence.).


John Spencer was granted "Licence to impark lands in Olthorp and Wykehamond, Northt." and "licence to castellete his manors of Olthorp, Northt., and Wormeleighton, Warw." by Henry VIII in 1512. Olthorp is clearly Althorp, now the site of C18 palladian house, still owned by the Spencer's. Wormleighton was the principle residence and John Spencer did rebuild the house there but the evidence for him building at Althorp is less certain and, although a earlier medieval house probably existed, it may be his grandson who built the current, very much altered, house.
How defensible that courtyard house was is uncertain, although at this late date, in a quiet inland county, it is unlikely to have had anything other than decorative battlements (Even these may be doubtful; Camden describes Robert Spenser, the likely actual builder, as a 'lover of vertue and learning' which may suggest his preferred architectural style would have been based on classical motifs). There is nothing to suggest a moat was ever built or intended.

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.
