Known as the "university church," Great St. Mary's has its origins in the 11th century, although the current building dates from 1478. The main reason to visit is to climb the 113-foot tower, which has a superb view over the colleges and marketplace (though it may be closed in bad weather). Also here is the Michaelhouse Centre, a small café, gallery, and performing arts venue with frequent free lunchtime concerts. Tours must be booked in advance; contact Helen Long at 01223/462914.
