The church was built on the site of Roman ruins and is dedicated to St Martin of Tours, a 4th century Roman officer who became a Bishop. It is almost certainly one of six churches referred to in the Domesday Book (1086) and portions of the current building can be traced to a 12th century Norman church which was rebuilt in the 13th and 15th centuries. In the Middle Ages, its site next to Leicester’s Guild Hall, ensured that St Martin’s became Leicester’s Civic Church with strong ties to the merchants and guilds of the town.
