Originally known as "The College," this pristine campus is the second oldest in the country (Harvard University is older). Stop off at the Sir Christopher Wren Building (a treasure in itself) for maps and information on self-guided tours. Romantics will want to follow the footpaths through the Sunken Garden and Crim Dell, where you may spy a wedding proposal by the pond. Self-guided walking tours are permitted on weekdays only. Free.
