St Joseph's Catholic church, Aberavon was built in 1930 to designs by F R Bates and Son in Early Christian style in red brick under slate roofs, with projecting boarded eaves and simple red brick dressings to small round-headed multi-pane windows. The interior is basilican with a three-tier stepped altar of dark green and white marble. The building replaced an earlier church of 1862.
