The Visitor Centre of the Royal Observatory Edinburgh is housed in the original Observatory Building, beneath the one of the iconic green telescope domes. Our purpose is to promote and respond to public interest in astronomy, support science education, and promote access to the work of the Royal Observatory Edinburgh.
