St Mary's Church, Luton

The architecture of St Mary's is varied as the church has been renovated and rebuilt many times, but the basic layout is that of a cruciform, with north–south aisles and many chapels and extensions in various directions heading off the main church. The total length of the church is 53 m, the total width is 17 m, and the height is 27 m. The outside of the church is clad in a distinctive flint and stone chequer, which makes the church stand out in the town. The graveyard in the direct vicinity of the church is no longer used, but a cemetery that covers most of St Anne's hill, the Luton Church Cemetery, is about a mile from the church, heading up to Crawley Green.

Much of the funding for the building has come from the Friends of St Mary's Luton who have raised over £1 million since 1965.

St Mary's currently stands in the Open Evangelical tradition of the Church of England. It has been known for its youth work in the town and its pioneering peace and reconciliation ministry The area next to St Mary's Church (Power Court) has been due to be renovated for years. Currently Luton Town Football Club have proposed to develop the site with a stadium and other facilities. The project has been granted planning permission and is due to be completed eventually.
