The lottery is handing over a £34,000 grant to help open some of Oxford's historic spots to the public.

The grant was secured by Oxford Preservation Trust for a week-long festival next June for local families and children.

The trust will be working closely with Oxford University to open buildings and spaces not normally accessible to the public.

The festival, entitled Opening Doors, Opening Minds, will feature an open city weekend for local families. Special events will include a concert in the amphitheatre of the Sad Business School and a youth parliament in the University's Convocation House.

There will also be an environmental competition at the University Museum of Natural History, a history of Oxford by drama students at Oxford Castle and a major project on Oxford Marmalade, connecting young people with the city's industrial heritage and "jam making".

Trust director Debbie Dance said: "We are delighted that the Heritage Lottery Fund has backed this project, and look forward to working with the university and many young people in the city.

"We are only just starting, but plans are coming together for children's trails and family events, some in rather unlikely places."

Dr John Hood, vice-chancellor of Oxford University, said: "We are pleased to be involved in a project which gives local families the chance to share and enjoy the rich heritage of the city and of the university.

"In particular it gives young people the opportunity to use historic and unusual venues as a stage for their activities."

Opening Doors, Opening Minds will take place between June 18 and 24 and will form part of Oxfordshire's celebrations of 1,000 years of history.
