Newhaven Fort, built in the 1860s to protect the harbour, is East Sussex’s largest defence work and today offers a fascinating mix of history and family-friendly exploration. The Victorian fortress sits high on the cliffs with sweeping Channel views and is filled with interactive exhibits, wartime memorabilia, and recreated Blitz and air raid shelters.
Visitors can wander through the echoing tunnels, explore restored gun emplacements, and learn about Britain’s coastal defences from the Victorian era through World War II. A café, gift shop, and a varied programme of seasonal family events make it a rewarding day out for all ages.
