St Nicholas Church is located in the centre of
North Walsham close to the marketplace, and surrounded by narrow streets. The building is about long internally, and approx. overall when the ruined tower is included. The body of the church has a mixture of
Decorated Gothic and
Perpendicular styles. The building has seven
bays running along its length. It lacks an arch to the entrance of the
chancel. In the west wall of the north aisle is a
lancet window. Most of the aisle windows have restored intersecting tracery. The main entrance doorway and the chancel are Decorated. The east window and east aisle windows were restored in 1874, and the 500-year-old medieval roof was replaced between 1875 and 1881. The pinnacled entrance porch is richly carved and decorated with colourful statues and heraldic emblems. During the medieval period the south chapel area of the church contained a
shrine to
Thomas Becket, popular with pilgrims en route to
Bromholm Priory at
Bacton. The porch is described by the architectural historian
Nikolaus Pevsner as "a showpiece of the late 14th century". The date is confirmed by the emblems of
Edward III and
John of Gaunt. The building is one of Britain's largest parish churches. The original size of the tower () meant that it was one of the tallest churches in Norfolk. The church’s two
piscinae were used for rinsing the sacred vessels after the
Eucharist On the north side of the south chapel an arch may be seen behind the
sedilia. Its function is unknown, but it may have been designed to increase the light level, or to permit an
unconfirmed or
excommunicated person could watch a church service. ==Furnishings and fixtures==
