Heritage Open Days allow free exploration
Hundreds of people are expected at Heritage Open Days all over Beds, Herts and Bucks this weekend.
The annual openings, established in 1994, allow visitors free access to properties that are usually closed, or would normally charge an entrance fee.
There will also be tours, events and activities that focus on local architecture and culture.
It is a unique opportunity to explore the sometimes hidden and interesting places in the UK.
In Buckinghamshire, the John Howard Barracks in Milton Keynes, which houses an operational TA company, is opening to the public for the first time.
Visitors can discover the history of some of the Bucks battalions in both picture and display form and see and hear stories from past encounters to the present day.
In other county events, Stowe Landscape Gardens will be open and visitors will be able to see inside the Gothic Temple, which is now a holiday cottage for the Landmark Trust.
In Hertfordshire, events include being able to see the law in action at St Albans Crown Court where visitors will be able to sit on juries, meet police and prison dogs and visit the cells, while in Berkhamstead staff at the National Film & Television Archive will be giving guided tours.
In Bedfordshire, the Walled Garden on the Luton Hoo estate will be open with displays about 10 years of its restoration project, and in Bedford the John Bunyan Museum and Bunyan Meeting Free Church will be offering guided tours of the church and meeting rooms, with extra history displays including one of the BBC's use of the hall in 1940s.
The library will also be open to the public, which can usually only be viewed by appointment only.
