Known for its magnificent cathedral, Ely is the "capital" of the fens, the center of what used to be a separate county called the Isle of Ely (literally "island of eels"). Until the land was drained in the 17th century, Ely was surrounded by treacherous marshland, which inhabitants crossed wearing stilts. Today Wicken Fen, a nature reserve 9 miles southeast of town (off A1123), preserves the sole remaining example of fenland in an undrained state.
Enveloped by fields of wheat, sugar beets, and carrots, Ely is a small, dense town that somewhat fails to live up to the high expectations created by its big attraction, its magnificent cathedral. The shopping area and market square lie to the north and lead down to the riverside, and the medieval buildings of the cathedral grounds and the King's School (which trains cathedral choristers) spread out to the south and west. Ely's most famous resident was Oliver Cromwell, whose house is now a museum.
