Local preacher Joseph Watts of Leigh on Mendip completed the return from the Primitive Methodist chapel in Shepton Mallet to the 1851 Census of Places of Public Religious worship.
He does not give us a date for the opening of the chapel , but confirms that it held 90 people. On Census Sunday, 47 attended in the afternoon and 73 in the evening. Mind you 140 scholars attended the morning Sunday school, which must have been quite a tight fit.
I cannot see a Primitive Methodist chapel on historic Ordnance Survey maps, although the 1867 registration of places of public religious worship does record a Primitive Methodist preaching house on Leg Street.
