The cathedral walls are clad in ashlar sandstone.
On the south wall is a porch, with a wrought iron gate and a sundial over the door arch.
The wall of the north aisle is the oldest part of the church dating from about 1150.
The nave piers date from the 12th and 13th centuries and the arcade and chancel arches date from the 14th century.
The late 15th-century chancel now serves as the choir.
 The nave's original stone vaulted roof has been replaced with wood.
The 15th-century wooden ceilings over the nave and aisles have carved bosses.

The current chancel, a transept and St Mark's Chapel were built at the east end in 1904 to designs by John Loughborough Pearson and completed by his son, Frank L Pearson.
The 20th-century chancel has a stone vaulted roof.

The cathedral's large four-stage west tower has angle buttresses and a very tall crocketed spire behind an embattled parapet with crocketed corner pinnacles and at 247 feet (75 m) tall, is the highest spire in Yorkshire.
