St Thomas is a former Anglican church in the Brightside area of Sheffield in England which now serves as a circus training school.

The Sheffield and Rotherham Railway opened in 1838, and both industry and housing spread along its route through the Lower Don Valley.

Despite its booming population, the district of Brightside did not have an Anglican church, the local congregation instead meeting in a licensed room with a capacity of only seventy people.

[4][5] A site of around one acre off Holywell Road was donated by the Earl Fitzwilliam, and construction began in 1852, Canon Blackburn laying the foundations stone.

[13] During the 1980s, it was used as the Sheffield School of Gymnastics,[14] then in 1995 it was restored as part of the TV series Challenge Anneka, to serve as a training centre for Greentop Circus.
