Lothian Cemetery is one of Delhi's oldest Christian burial grounds, tucked between Old Delhi's heavier monuments and the roads leading toward the Red Fort. It was used from 1808 to 1867 and includes graves connected with the 1857 uprising.
This is a quiet, specialist stop rather than a headline sight. It works best as a short detour while exploring Old Delhi's colonial and Mughal layers, especially if you are already walking between St James' Church and the Red Fort area.
