As of 8 June 2016 there are 922 churches included.
Most are Church of England or Roman Catholic plus a few Orthodox but there are also some that have passed to other groups or into non religious use.
Many churches are kept locked and for those there are only exterior shots but where possible there is a selection of internal shots to try to give a flavour of the building. Each posting also has some basic information about the church.
The map of Greater London shows which areas of London have coverage in this ongoing project.
Have a browse around or select from the categories (Architects and Places) listed on the left of each post.
