The description from the Church in Wales Diocese site is;-
The first St. Nicholas in Swansea was built in 1886 down by the docks as a mission church to the seafarers of that time. (It was closed in the 1920's but still exists as a building near the present Leisure Centre.)
The first church on Townhill was built as a mission church from the adjacent parish of St. Judes. This church is adjacent to the present church and now serves as the Church Hall.
It was made into a separate parish in 1937 - see St. Nicholas-on-the-hill, Townhill .
The present St. Nicholas was built with the aid of compensation given to the Church in Wales for Holy Trinity church destroyed in the blitz on Swansea in 1941. The Church registers date from 1924
