Carfax Tower
Passing through Carfax, the center of Oxford and where four roads meet, you can spot this tower. It's all that remains of St. Martin's Church, where Shakespeare stood as godfather for William Davenant, who himself became a playwright. Every 15 minutes, little mechanical "quarter boys" mark the passage of time on the tower front. Climb up the 99 steps of the dark stairwell for a good view of the town center.
