Fort Amherst – Tunnel Junction sits on the edge of Chatham’s historic waterfront, a coastal 18th‑century fortress designed to defend the Medway approaches. Its rugged ramparts and the labyrinth of tunnels carry the weight of maritime defense history, now layered with cinematic texture from modern productions. For The Witcher Season 3, the site provided atmospheric exteriors and backstage spaces—brick work, sea breeze, and dim tunnel corridors that heighten the sense of danger and mystery. Today the fort’s weathered stones and quiet coastline invite visitors to step into a place where history and fantasy intersect with palpable mood and frontier spirit.
