Visit Greenwich and you'll discover what makes Londoners tick. Situated on the Greenwich Meridian Line at 0° longitude, this smart Thames-side town literally marks the beginning of time. For an island nation whose reputation was built on sea-faring adventure, Britain's centuries-old maritime tradition lays anchor here. Fans of elegant architecture will be in heaven-on-sea, while landlubbers can wander acres of rolling parkland and immaculately kept gardens. And while the world-famous Cutty Sark may have long since unloaded its last tea chest, trading traditions live on in Greenwich's maze of market stalls that sell a Davy Jones locker's worth of bric-a-brac, antiques, and retro gear.
