Greenwich is a borough in London, England, on the banks of the River
Thames. Known for its maritime history, it's home to the Cutty Sark, a
restored 19th-century ship, the huge National Maritime Museum, and the
classical buildings of the Old Royal Naval College. The modern O2 arena
sits on a peninsula to the north. Overlooking peaceful Greenwich Park, the
Royal Observatory is the site of the Greenwich meridian line.
