Royal Museums Greenwich, Royal Observatory

Journey through space and time

Located in the UNESCO World Heritage site of Maritime Greenwich, the Royal Observatory offers an unforgettable backdrop for events. One of the most historically rich areas of London, the Observatory was built on the ruins of Greenwich Castle. Founded in 1675 by King Charles II, the Royal Observatory has been observing the stars for hundreds of years and is the home of Greenwich Mean Time (GMT).

From its hilltop setting in Greenwich Park, the Royal Observatory commands breath-taking views of Canary Wharf and the City of London. Flamsteed House is the original Observatory building designed by Sir Christopher Wren in 1675, with its elegant Octagon Room now being one of the few Christopher Wren-designed interiors that you can see in London today.
