Leicester Cathedral | 367 followers on LinkedIn. Leicester Cathedral - A beating heart for City and County. | Leicester Cathedral is at the physical heart of our city and county. Our church, built on the site of a Roman temple and dedicated to St Martin of Tours, has been embedded in the public, economic, cultural and religious life of this community since medieval times. Since 1927, as the seat of the Bishop of Leicester, we now gather people together for worship, celebration, lament, debate and service of the poor and vulnerable.
