Due to the large numbers of Irish people among the Catholic population of Liverpool, this building is also known jokingly as Paddy's Wigwam. In fairness, it does look like a wigwam or teepee. I much prefer Liverpool Cathedral, but the two buildings together do add a very pleasing variety to the skyline.

Hmm. This got downvoted. I'd like to distance myself from the racist slur contained in the information I noded. It wasn't my idea - why should factual writeups suffer?
