Historic sites will be open to the public for 10 days

A walking tour of Colchester's Roman and Medieval gates was part of the offering

Roman archaeological sites are being opened to the public as part of a 10-day heritage event.

Visitors to Colchester could explore areas of significant local interest - including a Victorian water tower and a World War Two airbase - from Friday.

It came as part of the National Trust's heritage open day scheme, whereby 45 attractions would be opened for free.

Mark Cory, head of resources at Colchester City Council, said there would be some "incredible heritage" spots on offer.

Construction of the 110ft (35m) tower, nicknamed Jumbo, began in 1882

The local authority said one of the star attractions would be a tour of the Balkerne Water Tower, affectionately known as Jumbo.

Other historic sites opening their doors included Colchester Castle and Hollytrees Museum.

Visitors could also see places where Roman archaeological digs have taken place in the city.

"It's a rare chance to step inside these unique places and discover the rich history of Colchester in a way you can't usually experience," Mr Cory added.
