The University Church of St Mary the Virgin, which I personally feel is a must among many of Oxford's attractions, must be the earliest and the first to visit, because it has a tower that is said to be one of the most beautiful minarets in Britain and the highest commanding height in the region, so it must be climbed. The ticket to climb the tower is 4 pounds for adults and 3 pounds for children. Because on the top of the tower, you can enjoy the whole Oxford Colleges, and only here can you take a picture of the Bodleian Library and the Universal College. It can be said that once you've been here, you don't have to go to Wanling College anymore. Ha-ha. However, the passageway at the top of the tower is not circular and must return to the original road. Therefore, the number of people climbing the tower is limited, and the passageway is very narrow, allowing only one person to pass through, so we must arrive early to avoid queuing and crowding.
