Construction of All Saints Cathedral began in 1871 and was completed in 1887, designed by Sir William Emerson, who also designed the Victoria Memorial in Kolkata. Consecrated in 1887, the cathedral was built to serve the growing Anglican community in Allahabad (now Prayagraj) during the British Raj. The cathedral's design reflects the Gothic Revival style, popular in Europe during the 19th century. It was intended to be a grand symbol of British presence and faith in India. Over the years, the cathedral has witnessed significant historical events and has remained an important religious and cultural landmark in the city. Its stained glass windows, including the impressive west window, depict scenes from the Bible and add to its historical and artistic value. The cathedral continues to serve as a place of worship and a reminder of Prayagraj's colonial heritage.
