[citation needed] The congregation selected David Bowen, to be its pastor, a position he held until his death in 1853.

[1] Zion Baptist Chapel was erected at a time when Llanelli had become a significant regional producer of tinplate and steel and the population was growing strongly and needed more buildings in which to worship.

It is the largest of the Baptist chapels in the town and has a three-bay façade with arched upper windows and a timber-pedimented porch.

There are giant pilasters in greyish-brown local stone contrasting with ornamentations in brown sandstone.

Two schoolrooms dating from 1913 and built by William Griffiths adjoin the chapel.
