CALSTOCK MANOR

Identity: confirmed — The supplied TNA/MDR record F292161, authority GB/NNAF/M317547, primary name Calstock Manor, historical variants Coldstick and Goldstick, and Calstock/Cornwall location identify the Duchy manor of Calstock rather than a same-named manor elsewhere.
Representative point: 50.4962, -4.2057
Basis: documented_manor_house — The former Old Post Office in Calstock is identified in local historical research as the building that served as the administrative centre of Calstock Manor and was known historically as the Manor House. Its mapped coordinates are approximately 50.4962, -4.2057 (OS grid SX436685). Medieval archaeological research cautions that the precise medieval manor-house location is uncertain, but places it probably near Calstock church; therefore this point represents the documented later manor-house/administrative site, not a proven medieval building footprint.

Boundary confidence: none
Boundary basis: Available sources establish Calstock Manor as a substantial Duchy of Cornwall manor associated with Calstock parish and lands including Harewood, Tamar-side woods and other constituent estates, but no accessible source provides a sufficiently explicit, source-mappable historical manorial perimeter. The existence of an 1840 Manor map in the Calstock Parish Archive is a strong research lead, but the map was not available here for boundary reconstruction. The parish boundary has not been substituted for the manor boundary.

- The Parochial History of Cornwall, Volume 1: Calstock: https://en.wikisource.org/wiki/The_Parochial_History_of_Cornwall/Volume_1/Calstock — Describes Calstock as a manor of the Earls/Dukes of Cornwall, records its Tamar fishing rights, and states that the manor was sold by the Duchy and ultimately became the property of John Williams. It also places the manor within the historical Calstock landscape.
- Calstock Parish Local History Group: Collections: https://www.calstockhistory.org.uk/collections.html — Confirms the archive holds a 1840 Manor map, 1815 survey, tithe material, manorial maps and extensive Duchy manor records, demonstrating that detailed boundary evidence exists locally but is not reproduced online on the page.

- The Old Post Office, Calstock: mapped location and listing data: https://britishlistedbuildings.co.uk/101329362-the-old-post-office-calstock/maps — Provides the mapped coordinates 50.4962, -4.2057 and OS grid reference SX436685 for the Old Post Office, used as the representative point.
- Cornish Archaeology No. 29: Calstock archaeological research: https://cornisharchaeology.org.uk/app/uploads/2022/08/No.29_1990.pdf — Notes that the medieval Calstock manor house location is uncertain, was probably near Calstock church, and was not at Harewood; this limits confidence in treating the later administrative site as the original medieval manor-house location.
Warnings / uncertainty:
- No historically defensible manorial boundary polygon was located in the accessible sources; do not inject a polygon based on the modern civil or ecclesiastical parish boundary.
- The representative point is based on the documented later manor-house/administrative site at the Old Post Office area, while the precise medieval manor-house location remains uncertain and may have been nearer Calstock church.
- The 1840 Manor map and related local archive material should be consulted before attempting a boundary reconstruction.
