The world-famous Meridian Line

Views of London  
Take in one of London’s most-loved views across historic royal Greenwich, Greenwich Royal Park, the City of London and the River Thames. It is the perfect place for a group photo with the ever-changing London skyline in the background.  
The Octagon Room  
The Octagon Room, completed in 1676, is the oldest part of the Royal Observatory and the centrepiece of Flamsteed House. With its big windows, the room was perfect for watching the sky. Designed by Sir Christopher Wren, it is one of the best-preserved Wren interiors in London. 
Harrison’s clocks  
See the revolutionary Harrison’s clocks – the clocks that changed the world. Also, discover the Shepherd Gate Clock, mounted outside, which was the first clock to show Greenwich Mean Time to the public. 

Great Equatorial Telescope
