In 1672 a house in Malmesbury may have been licensed for Baptist meetings and a Meeting was definitely in existence by 1688 in Abbey Row. A pastor was appointed in 1689 and a chapel was built at Abbey Row in Westport parish in, or just after, 1695. This was a low stone building that seated between 60 and 70 people and baptisms took place in the river Avon near Mill Lane.
In 1802 the present chapel was built for the Strict Baptists. In was enlarged by the addition of galleries in 1814 and in 1816 the north end was demolished and the chapel lengthened. This would indicate that the movement was flourishing at this period. The chapel was refurbished in 1910 and continued in use until the mid 1980s. In 1997 it was bought by the King's Church.
