St Mark's is the Anglican parish church of New Swindon. It was built between 1843 and 1845 to designs by Scott and Moffatt as part of a desire to provide spritual and educational facilities for the workers employed at the nearby Great Western Railway works.
The tower and spire were built to the north side of the nave to improve the view of the church from the nearby railway line.
