Notre Dame University Church, the Cathedral of Oxford University, has a thousand years of history. It is situated on the side of Oxford High Street. Its high bell tower and magnificent appearance are also landmarks of the ancient city of Oxford. Visits to churches are free, tickets for 4 are required to climb the Bell Tower, and there are many visitors waiting in line to climb the Bell Tower, but it feels very worthwhile to climb the Bell Tower and have a panoramic view of Oxford.
