There are two entrance porches, each with two storeys. The south, or Duke's Porch, was given by Lionel, Duke of Clarence and is marked with his coronet. It is the earlier of the two porches, built between 1362 and 1368. It has a star-shaped tierceron vault and two smaller side entrances. The north, or King's Porch, was given to the church by King Edward IV and bears his arms. It is the taller and more elaborate of the two, with a ribbed vault with liernes and bosses, a castellated turret and, above the entrance, two escutcheons, carved niches and a figure-frieze. At the top, underneath the pinnacles on each side is a carved wodewose or savage man holding a club. The room above the north porch was dedicated by Conrad Noel as a chapel to John Ball, a leader of the Peasants' Revolt. The church is usually entered through the North Porch, off Watling Street.
