Carfax Tower, located in the center of Oxford in the 13th century, was built in 1035. Carfax originated from French carrefour, which means crossroads. In 1896, in order to improve the city church, the main part of St. Martin was demolished, leaving only the bell tower, 23 meters high. Nowadays, no more than that height can be built in Oxford. Look down from the top of the tower. It feels like Walter was defending Sarajevo.
