The fort was commissioned by Lord Palmerston to protect Plymouth from the threat of Napoleon III's navy.
Its construction features a 'ditch' defense system, where the fort is protected by a deep dry moat carved into the hillside.
The structure is partially subterranean, with rooms carved into the bedrock to withstand artillery fire.
It is often referred to as a 'Palmerston Folly' because the invasion it was built to prevent never materialized.
The fort's roof was originally designed to be bombproof and was used as an active defensive position.
The site includes a secret tunnel known as a 'caponier' which allowed soldiers to fire along the length of the dry moat.
Polhawn Fort is a Napoleonic-era coastal fortification situated on the Rame Peninsula in Cornwall, overlooking Whitsand Bay. Originally constructed in the 1860s as one of the 'Palmerston Forts' designed to defend Plymouth Sound from a potential French naval invasion, it has been repurposed as a private venue. The site is built directly into the cliffside, featuring thick stone walls, vaulted ceilings, and a private path leading to a secluded beach. It operates primarily as a destination for weddings and exclusive events, offering historical military architecture with modern amenities. The fort remains a significant example of Victorian defensive engineering, retaining its original gun emplacements and defensive earthworks. Access to the interior is typically restricted to booked events or scheduled viewings.

Check the official website for open days, as the fort is not open for general tourism outside of booked events or specific public viewing dates.
Bring sturdy footwear if planning to explore the steep, rugged coastal path that descends to the beach.
Check local weather forecasts before visiting, as the exposed cliffside location is subject to high winds.
Do not attempt to walk on the cliff edges, as the terrain is unstable; avoid visiting during extreme weather alerts for the South West coast.
The fort is exclusively hired for private events; it is not open to the public for walk-in visits.
Respect private event signage; if attending a private function, adhere to the host's specific dress code.
