Greenwich sits on the south bank of the River Thames in south‑east London, within the Royal Borough of Greenwich. It is best known for its maritime and scientific heritage – the Royal Observatory and the Prime Meridian that define Greenwich Mean Time sit above the town, and the area’s UNESCO‑listed ensemble includes the Old Royal Naval College, the preserved tea clipper Cutty Sark and the National Maritime Museum, all backed by the green sweep of Greenwich Park.
Today Greenwich is a busy mix of tourists and local life, with craft stalls and food at Greenwich Market, academic presence from the University of Greenwich, and riverside regeneration around the Greenwich Peninsula and The O2. Good transport links and a strong community scene mean it combines important historic attractions with a lively cultural and economic hub.
