There's plenty to see at one of the oldest, best-preserved, and most comely of the Inns of Court -- from the Chancery Lane Tudor brick gatehouse to the wide-open, tree-lined, atmospheric Lincoln's Inn Fields and the 15th-century chapel remodeled by Inigo Jones in 1620. The wisteria-clad New Square, London's only complete 17th-century square, is not the newest part of the complex; in fact, the oldest-looking buildings are the 1845 Hall and Library, which you must obtain the porter's permission to enter.
