History
Established in 1675 by King Charles II and designed in part by Sir Christopher Wren, the Observatory defined GMT and the Prime Meridian used for global navigation.
Conservation
As an urban heritage site, visitors are asked to stay on paths and respect fragile instruments; light pollution limits stargazing—public programs aim to foster astronomy education rather than raw dark-sky viewing.
Reserve your spot on the UK London Royal Observatory today and enjoy a trusted, highly rated experience designed to help you make the most of your adventure.
Reserve a planetarium show time
Planetarium performances have limited seating—book the show time in advance to avoid disappointment.
Use public transport or riverboat
DLR to Cutty Sark or a Thames river boat drops you within easy walking distance and avoids congestion.
Bring a light jacket
The Observatory sits on a hill where wind can be stronger than at street level—layers make the outdoor Meridian experience comfortable.
Arrive early for the grounds and galleries
Allow time to visit Flamsteed House, the Meridian line and the gardens before the planetarium show to get the full context.
Comfortable walking shoes
Good footwear helps on the park paths and the short climb to the Meridian.
Layered jacket
Wind at the hilltop can be brisk—layers keep you comfortable between indoor exhibits.
