During a recent two-week, self-guided pilgrimage, we set out to discover Catholic London, traveling across the city on foot, by bus, and on the Underground. A highlight of our pilgrimage was Westminster Cathedral, the mother church of Catholics in England and Wales. There we encountered a form of Catholic worship that preserves elements of England’s Anglican heritage while remaining fully Catholic. No pilgrimage to Catholic London would be complete without a visit to the Brompton Oratory. Our pilgrimage to Catholic London was not simply a visit to historic sites, but an encounter with a faith that continues to inspire and endure.
