The Royal Observatory in Greenwich: Entry Ticket

The Royal Observatory, Greenwich , located in London, is the birthplace of Greenwich Mean Time (GMT) and the famous Prime Meridian (0° 0' 0") , the reference point for calculating time and longitude throughout the world.
Designed by architect Sir Christopher Wren , the Observatory was built to determine longitude at sea and today houses a fascinating museum dedicated to time and astronomy.

Inside, you can admire the first clocks created by Thomas Tompion and discover the extraordinary innovations in maritime navigation that made Britain a leader in exploration and global trade.
