The new cathedral, designed by Sir Frederic Gibberd and consecrated in 1967. was built over the crypt.
The church is circular in shape with chapels built in between the buttresses which support the tent-shaped spire (which represents the crown of thorns of Jesus Christ) like tent poles.
The church's exterior is concrete, which has not worn well and suffers from leaks. There is a belfry to the east of the church. A new stepped approach has recently been built.
The cathedral stands on the site of the Liverpool Workhouse.
