Tell me more

King Charles II commissioned Sir Christopher Wren in the 17th century to design the Royal Observatory. This landmark would give scientists a space to better understand the stars, which would help seamen navigate oceans by night.

Located atop a picturesque hill in Greenwich Park, the Royal Observatory was established in 1675 and has played a major role in astronomy. Seated on the south side of the River Thames, the Royal Observatory offers stunning views of England’s capital and is home to a wealth of knowledge about scientific studies.

Known for its red bricks, white trim accents, and dome-like flourishes atop the building, the Royal Observatory is an architectural icon in London. It attracts visitors year-round to educate them about the evolution of astronomy and England’s role in advancing the field. By day, see London from a unique vantage, and by night, delight in the green laser projected from the observatory that represents the Prime Meridian line.

Visitors can also learn about the history of Greenwich Mean Time and how the Greenwich Meridian was chosen to be the world’s Prime Meridian. The designation of that line, in 1884, went on to help establish time zones and stargazing clarity.
