Park Street Church, Upper Park Street, was established for the English-speaking members of Capel Als.

In 1829 David Rees came to Llanelli and took his first pastorate as an Independent Minister at Capel Als Church. He is said to have become concerned about the spiritual needs of the English speaking members of the congregation who had come to Llanelli to work in the emerging new industries. To accommodate his small English speaking congregation he held services for them after the morning Welsh service at Capel Als. Because of the response he had from this he decided to establish an English Congregational Church donating £10 himself.

The completed building cost about £650 which included furnishings and on 7 July 1839, it was formally constituted as a Church, with 27 members, 24 of whom were members of Capel Als.

Later, a Mechanics Institute was founded in the schoolroom at the back of the Church which also became the home of the first public library.

In 1865, because of a financial dispute over the renewal of the lease, the Church transferred to Murray Street where the new Park Church was opened in September.

The building that once held services for the English speaking members of Park Independent Church now [2002] houses the frozen food firm of Iceland.
