The first church was built on the site of Christ Church Cathedral in Lisburn in the early 1600s by Sir Fulke Conway as a chapel of ease for his new castle at what was then called Lisnagarvey. It was consecrated in 1623 and dedicated to St Thomas, but was destroyed along with much of the town during the rebellion of 1641.
The church was quickly rebuilt and in 1662 St Thomas's was designated the cathedral church and episcopal seat of the United Diocese of Down and Connor by Charles II and renamed Christ Church Cathedral. Additional gallery seating was introduced in 1674 with access via a bell tower. The cathedral burned down a second time in 1707.
Again it was quickly rebuilt starting in the 1708 and completed 11 years much after in the (1719), retaining the galleries in the nave with access via the tower which had survived the fire. The octagonal spire was added in 1804 and the chancel built and consecrated in 1889. In the year of 2003, the 1796 front gates were replaced and in 2004 the clock chimes refurbished.
On 31 July 1914 protesting Suffragettes bombed the Cathedral. A small explosion blew out one of the oldest stained glass windows. Four women arrested after the attack.
References:The Church of St Donatus name refers to Donatus of Zadar, who began construction on this church in the 9th century and ended it on the northeastern part of the Roman forum. It is the largest Pre-Romanesque building in Croatia.
The beginning of the building of the church was placed to the second half of the 8th century, and it is supposed to have been completed in the 9th century. The Zadar bishop and diplomat Donat (8th and 9th centuries) is credited with the building of the church. He led the representations of the Dalmatian cities to Constantinople and Charles the Great, which is why this church bears slight resemblance to Charlemagne's court chapels, especially the one in Aachen, and also to the Basilica of San Vitale in Ravenna. It belongs to the Pre-Romanesque architectural period.
The circular church, formerly domed, is 27 m high and is characterised by simplicity and technical primitivism.
