The Chapel Royal of St Peter ad Vincula ("St Peter in chains") is a Chapel Royal and the former parish church of the Tower of London. The chapel's name refers to the story of Saint Peter's imprisonment under Herod Agrippa in Jerusalem. Situated within the Tower's Inner Ward, its current building dates from 1520, although the church was likely established in the 12th century. The church for working residents was the second chapel established in the Tower after St John's, a smaller royal chapel built into the 11th century White Tower. A royal peculiar, under the jurisdiction of the monarch, the priest responsible for these chapels is the chaplain of the Tower, a canon and member of the Ecclesiastical Household. The canonry was abolished in 1685 but reinstated in 2012. Read more on Wikipedia
