A host of buildings and attractions in King’s Lynn and West Norfolk will celebrate Heritage Open Day on Sunday.

The annual event is a tribute to local architecture and history and will see a number of venues open to the public which usually have their doors closed.

Thousands of visitors are expected to attend the event which is organised in conjunction with the town’s civic society.

Houses, offices, gardens, churches, some cemeteries, towers, tunnels and other buildings will be open from 10am to 4pm on Sunday.

There will also be the chance to visit pontoons at South Quay, ride on a miniature train in The Walks, see classic cars in a showcase event on the Tuesday Market Place, organised by West Norfolk Council, visit tunnels under the market place and tour the town via a free vintage bus.

There will be a chance to explore the wine vaults at the Bank House in King’s Staithe Square, climb the bell tower at the Minster, visit the library tower in London Road, and climb the tower at the privately-owned Clifton House in Queen Street.

Actors will bring the past to life with period costume to add colour to the open day.

The drama and acting will take place at various venues around the town, along with dancing, music, walks, talks and exhibitions.

There will be special activities for children at Baxter’s Plain (near the former Beales) where youngsters can make their own coat of arms.

The Hardwick Road Cemetery will be open for visitors, along with the Jewish Cemetery in the Millfleet.
