All Saints Cathedral, Prayagraj, Anglican cathedral in Civil Lines, Prayagraj, India.

All Saints Cathedral, known locally as Patthar Girja (Church of Stones), stands at the crossing of MG Marg and SN Marg in Prayagraj. Its cream-coloured stone walls have red sandstone dressings and a roof of local red tiles. The nave is about 40 feet wide and 130 feet long, with narrow aisles, north and south transepts, a chancel with ambulatory, and a central lantern tower called Victoria Tower.

The cathedral was founded in 1871 when Sir William Muir donated the land and his wife Elizabeth laid the foundation stone. The completion of this Gothic Revival structure followed during the years of British colonial presence in the region.

Locals call it Patthar Girja, the Church of Stones, for its cream-coloured stone walls with red sandstone dressings. The cathedral keeps All Saints' Day on 1 November as its anniversary and has belonged to the Church of North India since 1970. Inside, plaques record the deaths of British nationals in India for various causes.

The cathedral stands in a large open space at the crossing of MG Marg and SN Marg, the road also known as Sarojini Naidu Marg. The nave is about 40 feet wide and 130 feet long, with narrow aisles bringing the internal width to about 56 feet; seating was planned for 300 to 400 people. Visitors enter through the west porch, and the church is surrounded by a garden.

The lantern tower at the crossing of the nave and transepts is called Victoria Tower and serves as a memorial to Queen Victoria. The pulpit, carved in alabaster by Mr Nicholls of Lambeth to William Emerson's designs, is a piece of workmanship visitors often pass by.
