As a member of this church, 2 of the reviews below are not for this cathedral. I'm thinking they were confused between London, England and London, Canada.
However, this church as mentioned has 4 original Tiffany windows. The only church in London with such. Many, many artifacts on display that connect this Cathedral with the history of London. Remembrances for a lot of local people who have made significant contributions to the history of London. A lot of military history displayed going back right to the Crimean war.
Check out St Aidan's chapel with its tapestries.
A beautiful organ used during services and on Tuesday lunch hour recitals
