Fort Amherst is a Napoleonic-era coastal fortress that rises above the river with brick ramparts, gun batteries and shadowed tunnels, a testament to 18th-century military engineering. The site sits beside the rustic Jolly Farm barn, creating a stark contrast between formidable fortifications and rural outbuildings. Its weathered walls and expansive exposure have made it a magnet for filmmakers seeking authentic period atmosphere, and it was used as a location for The Witcher Season 3. Today the ramparts offer a contemplative stage where history and cinema intersect, with visitors tracing the lines of a storied frontier.

Nestled on the Medway estuary, Fort Amherst is an 18th‑century coastal fortification whose red-brick ramparts, earthwork ditch, and sea‑touched battlements evoke a storied era of coastal defense. Its strategic position guarding the approaches to Chatham Dockyard lends the site a stark, atmospheric mood that filmmakers seek when chasing rugged, authentic backdrops. For The Witcher Season 3, Fort Amherst and the nearby Jolly Farm barn were repurposed to stage siege-inspired exteriors, lending real scale and grit to key sequences. Today the fort invites visitors to imagine the echoes of marching troops and whispered councils as gulls wheel above the river and the past feels palpably close.
