Oxford's little known sights opened their doors to record numbers of people at the weekend.

More than 30 locations were exclusively opened to the public to allow a peek inside the city's most interesting buildings and spaces.

Oxford Preservation Trust director Debbie Dance, who organised the Oxford Open Doors event, said: "It's been incredible. We've had about three times as many people this year than last year, when we had about 8,000.

"I think more people have got to know about it, and it's been good weather. There must be a taste for it."

Visitors were able to catch a ride on an authentic Oxford vintage bus to the Oxford Bus Company's depot, or visit Rewley Road fire station in the city centre.

The newly restored Regal Cinema, in East Oxford, also open its doors, as did the Ashmolean Museum, where visitors were able to inspect the redevelopment work taking place.

Guided walks took hundreds of people around Oxford Castle, the city's historic waterways and ghost trails, while others relaxed in normally closed gardens Tours around eco-homes and numerous exhibitions also drew the crowds.

Ms Dance added: "There were people all over the place, people in deckchairs enjoying the sunshine — they've been streaming in everywhere all day.

"The sheer numbers of people has been the highlight and seeing all the residents looking at all the things in Oxford they might not be able to get into otherwise.

"People have put time aside to see their city — people make time to do that sort of thing on holiday, but they've been able to do it here in Oxford.

"This has allowed people to see behind all the doors, and see and enjoy the city and the university together.

"Oxford is an amazing place to do this kind of thing and I think we'll do it for years to come.

"Every year, I think, there will be different and more things to do."

The Open Doors event formed part of the national Heritage Open Days scheme.
