The guild church of St Mary Aldermary in the City of London is probably named for being the oldest church dedicated to Mary in the city, though the current church dates from 1510. However, this was on the site of an older church dating from the Norman period.
The new church was financed by Sir Henry Keeble. however, when he died in 1519 the church was unfinished. Indeed, it was not completed until 1629! Unfortunately, the church was badly damaged a few decades later in the Great Fire of London in 1666 and was rebuilt in the Gothic Revival style.
The church has six bay aisles. It has a short chancel and a tower to the south west. The church is built from Portland stone.
