Our View

Substantial remains of a small 16th-century gun tower protecting Old Grimsby harbour. Built by Edward VI to defend England from French attack. Ironically the only military action it saw was during the interregnum after the Civil War, when it was occupied by Royalists who then came under Parliamentarian attack. It eventually fell to the Roundheads in 1651. A battery of guns was maintained here until the mid-18th century, after which it fell into disrepair. Its remains overlook a white sandy beach.

About the area

Discover Cornwall & Isles of Scilly

Cornwall has just about everything – wild moorland landscapes, glorious river valley scenery, picturesque villages and miles of breathtaking coastline. With more than 80 surfing spots, there are plenty of sporting enthusiasts who also make their way here to enjoy wave-surfing, kite surfing and blokarting.

In recent years, new or restored visitor attractions have attracted even more visitors to the region; the Eden Project is famous for its giant geodesic domes housing exotic plants from different parts of the globe, while nearby the Lost Gardens of Heligan has impressive kitchen gardens and a wildlife hide.
