A bit about us

Learn about the history of the Chilterns

Step back in time and explore over 30 reconstructed historic buildings, including an Iron Age roundhouse, 1940s prefab, blacksmith’s forge, Victorian toll house, tin chapel, WW1 and WW2 Nissen huts, earthen cottage and working historic farm that is home to  goats, sheep, chickens, cows and farm cats. All set in 45 acres of beautiful Chilterns countryside.

As well as a collection of historical buildings the Museum boasts a number of small traditional gardens that complement them and suit their time periods. These include a formal Arts and Crafts garden, a pretty cottage garden, and a ‘dig for victory’ allotment next to the 1940s prefab. The cherry and apple orchards are full of heritage varieties, and the woods are carpeted with bluebells in spring.

In addition to the buildings and gardens there is a heritage adventure playground, woodland trail, sensory trail, orienteering course, gift shop and Tea Room. The site is dog friendly and dogs on short leads are welcome.

The Museum has accessible toilets and baby changing facilities.

There are wheelchair ramps into buildings. The Museum's pathways are compact gravel which doesn't give the smoothest wheel chair ride. However, the Museum has a number of mobility scooters that are available to use free of charge, we recommend booking these in advance to ensure that they are available. The Museum also has a golf buggy and can offer lifts for those with limited mobility.

Small portable loop systems are installed at the Ticket Office and Tea Rooms for use by visitors with hearing aids.
