History of the united parishes of Saint Mary Aldermary, Saint Thomas Apostle, Saint Antholin Budge Row and Saint John the Baptist Walbrook:
The church of Saint Thomas the Apostle was situated in Queen Street. It is first mentioned in records in 1170, and was rebuilt in 1371. The building was destroyed during the Great Fire of London in 1666 and was not rebuilt. The parish was united with Saint Mary Aldermanbury (P69/MRY2) in 1670. The burial ground was partially cleared in 1851 for the widening of Queen Street.
The parish of Saint Mary Aldermary is 11th century in origin. The parish church was rebuilt after the Great Fire of 1666 and, in 1670, the parish was united with Saint Thomas Apostle. The parish church of Saint Antholin Budge Row was also rebuilt after the Great Fire and, in 1670, the parish was united with Saint John the Baptist Walbrook. Finally, the four parishes were united with each other in 1873 and the church of Saint Antholin was demolished the following year.
