The cathedral was dedicated in 1808, but was extensively damaged by an act of arson in 1820. George Richard Pain undertook the restoration of the cathedral. In 1964 the sanctuary of the cathedral was extended, and a sanctuary tower was built. As well as this, the internal layout of the cathedral was reorganised.
The most recent large-scale works were undertaken at the cathedral in 1996. The tower and sanctuary were renovated and refurbished, the roof was re-slated and the gothic ceiling was repaired. External stonework of the cathedral was also repointed. The cathedral closed for the duration of the works.
