The Collegiate church of St Peter is a large church in the centre of Wolverhampton. The church has Saxon origins though the oldest parts of the current church date from the 13th century, the crossing and south transept (of the cruciform layout). The nave dates from the 15th century, as does the tower and north transept and chancel. The church has a six bay aisled nave and a four bay chancel.
The church was a chapel royal for many years and a royal peculiar which meant it was independent of the local diocese and even the Province of Canterbury.
