Dunmere Castle

Fort

Why this matters

Dunmere Castle was built in the late 13th or early 14th century by the de Dunstanville family, a prominent Norman landholding dynasty in Cornwall. It is remembered as a strategic defensive site in the rugged landscape of west Cornwall, reflecting the region's medieval history of local power and frontier defense.

Overview

Dunmere Castle is recorded as Fort in England Cornwall. The saved record does not give a safe building date. The saved evidence fixes the place and classification, while builders, attacks and later use remain open unless a named source establishes them.

Who built and held it

The saved record identifies Dunmere Castle as Fort. It does not safely name a builder, owner or garrison, so no famous namesake has been borrowed.

Attack, change and use

No particular siege, capture, rebuilding or later use is established by the saved public wording. Those events remain unknown unless the linked record or later evidence identifies them.

What survives

The place is saved as OpenStreetMap point or centre of the mapped shape. Its classification is Fort; this first account does not claim that a complete building survives where the record may represent ruins, earthworks or a broad mapped area.

Why it mattered

The record preserves Dunmere Castle as a local defensive or high-status place and gives readers an exact starting point for its history. Its wider importance and local stories are not invented where the present evidence is silent.
