In 1672, the congregation led by Bunyan purchased a barn which they used to conduct worship. Eventually, a church, which came to be called the Bunyan Meeting Free Church, was built on the site of the barn. In 1849, a second church was built which is still used for services. A separate museum building was constructed in the compound in 1998 and the Bunyan artefacts and memorabilia formerly housed in a small museum room in the church were moved into it.
The museum's displays recreate a number of scenes from Bunyan's life which also show some of Bedford's social history in the seventeenth century. In addition there are artefacts such as Bunyan's iron violin and wooden flute, Bunyan's stoneware jug he used in prison as well as his will and a third edition of The Pilgrim's Progress.
