Designed by distinguished Lancaster architect Edward Paley in the style of 1300, the building was completed in two phases - in 1857-59 and 1895-96 - initially as a parish church. It replaced the first purpose-built Catholic church in Dalton Square (which today is Palatine Hall, offices of the City Council).
It was consecrated in 1859 and raised to Cathedral status for the Roman Catholic Diocese of Lancaster in 1924. The Presbytery next door was designed by Paley and Austin. The Cathedral tower stands at 240ft tall and contains a peel of ten bells, possibly the only Catholic church in England with so many bells. The Cathedral has recently undergone extensive restoration work and its interior is now a place of great beauty and dignity. Open daily for services between 8.00am and 7.00pm.
