Regarding Great St. Mary’s Datum. William Warren chose Great St. Mary’s Church as the starting point for his milestone series. This church, also known as the University Church, has dominated the Cambridge marketplace for more than 800 years. Its belfry was added in 1593, and by 1608 its main tower reached its present height of 114 feet. Visitors can climb the 123 steps for a panoramic view of Cambridge and the surrounding countryside. (These details are from the flyer visitors receive when they climb the tower.)
