The award-winning Time galleries, featuring John Harrison's celebrated timekeepers, explore our need for accurate timekeeping and the role it plays in our everyday lives. The galleries are located in the north part of the Observatory site, in Flamsteed House, the Meridian Building and the Great Equatorial Building (see floor plans). Please note that charges apply for this part of the site – see Times and admissions for details and to buy your ticket.
Entrance is FREE to the interactive Weller Astronomy galleries, located in the Astronomy Centre in the south part of the Observatory site. Touch a 4.5 billion year-old meteorite, watch how the universe was formed, unravel the mysteries of the cosmos with help from our on-screen experts, and guide a space mission.
