The Union Baptist Chapel in the High Street was opened in 1898, replacing the chapel on the Green. An extract from the Northampton Mercury, published Friday 6th November 1891, stated. “It is contemplated to erect a new Union Church at Deanshanger. The effort has already gained considerable ground, and handsome subscriptions have been received. Mr. E. Roberts contributed £100 for the site, and Mr. H. Roberts £100. No doubt the effort is highly appreciated by the inhabitants of the constantly increasing village of Deanshanger”.
The chapel ceased to be a place of religious worship in 1980, although it may not have been in use for some time prior to this. The building has since had a variety of uses, including commercial premises as a book depository. It is now a private residence.
