St George the Martyr, Southwark, is a Church of England parish church located on Borough High Street at the junction with Long Lane, Marshalsea Road, and Tabard Street in Southwark, London. It is a Grade II* listed building designed by architect John Price in a neoclassical style, with construction completed between 1734 and 1736. The church replaced an earlier medieval building dating back to at least 1122, making it one of the oldest dedications to St George in England, likely linked to the Crusades.
The church has strong historical associations with Charles Dickens, whose father was imprisoned in the nearby Marshalsea prison. Dickens lived close by during his youth, and St George’s features in his novel Little Dorrit, with a small representation of Little Dorrit in the church’s east window.
Historically, the church was significant in the 15th century when Henry V was welcomed there after his victory at the Battle of Agincourt in 1415, a battle where the red-on-white St George’s Cross was first used as England’s patron saint symbol
 
interesting fact.
The surviving wall of Marshalsea prison still adjoins the churchyard.
The church tower has four clock faces—three are white and illuminated, but the east-facing clock towards Bermondsey is black and unlit. Legend says this is because Bermondsey residents refused to contribute to the church’s construction costs
