John Bunyan, author of The Pilgrim's Progress, frequently preached in this part of Hertfordshire.  The chimney stack, standing in its own public garden, is all that remains of one of the cottages where he is believed to have evangelised.  The cottage was constructed in the 17th century but the rest of it was demolished in 1877 when the agricultural cottages across the road were built.

The chimney and public garden are located in the hamlet of Coleman Green.
