Vanished possible C12 castle near Penzance. Grade 2-star listed C18 house on presumed site. From Polsue - About a quarter of a mile to the west of Penzance is Castle Horneck, the Iron-castle thought to be the site of a castle so denominated from its supposed strength, and built by the family of Tyes, who were lords of this district early in the times of the Plantagenets, and whose title as baron Tyes became extinct in 1322. "Castle Hornocke, " writes Norden , "an auntient ruyned castle standinge on a mounte nere Pensans , and as it seemeth in former times of some accompte." (Spreadbury)

Norden refers to Castle Horneck as an ancient ruined castle standing on a mount near Penzance. A note in the Western Antiquary states: "Castle Horneck (iron castle) ancient baronial castle of Baron Tyes, small remnant built into the eighteenth century mansion of the Borlase family." The OS suggests that Castle Horneck was once the name for Lesingey Round. In 1696 a field name at Lesingey was "Castle Close". The place name "Castle Horneck" survives as the name of a farm and house 400m east of Lesingey Round, currently in use as a Youth Hostel. (Cornwall & Scilly HER)


Norden is, presumably, John Norden, C16 cartographer. PastScape mentions post-medieval house only. This site is about 400m east of Lesingey Round, sometimes suggested as the site of a castle on morphological grounds, and it is possible that this is the site of the C12 castle and that the place name has been utilised by a later building on a nearby but different site.

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.
