FOR the first time this year Devonport Naval Base Heritage Site is throwing open its gates to visitors.

On Sunday (March 22) between 10am-4pm members of the public will be able to glimpse our rich maritime history.

The theme is to celebrate the valued efforts of the Polish Armed Forces in Devonport and Plymouth during WW2.

As well as historical exhibitions displayed through eight galleries, visitors can enjoy boat trips around warships alongside at the Naval Base and book a guided tour to the cold war submarine, HMS Courageous.

Through the Naval Heritage Centre you can discover how the dockyard of the 1690s has grown into the largest Naval Base in Western Europe, and led to the creation of both Devonport and Torpoint.

The Naval Base Executive Officer, Commander Paul Haycock said: “This is our first heritage open day of the year and it’s a wonderful opportunity for people to immerse themselves in the history and heritage of both Devonport and the Royal Navy.

"Visitors will be able to book free boat trips around the Naval Base to see ships alongside and also gain a fascinating glimpse into the world of the “Silent Service” by getting on a guided tour of the nuclear-powered submarine Courageous.

"We look forward to seeing you and sharing the outstanding and unique treasures of our heritage centre.’’

The entrance to the Heritage Site is via Granby Way in Devonport, opening times will be between 10am-4pm. Entry to the event is free with nearby free parking.

The café will be open for drinks, home-made cakes, pasties and snacks. Programmes will be available on the gate and donations to help maintain the exhibitions are welcomed.
