How to access the Shepherd Gate Clock

Royal Observatory Greenwich Shepherd Gate Clock

The Shepherd Gate Clock is free to view, and you don't need a ticket for the clock itself. It is mounted on the exterior wall beside the double gates leading into the Royal Observatory Courtyard in Greenwich Park. You can admire its distinctive 24-hour dial without entering the paid attraction. If you'd like to explore the historic Observatory, its astronomy displays and the

  • Plan your visit: The Royal Observatory is scheduled to close to the public from 2 November 2026 for a major transformation project. Check current access arrangements before travelling, particularly if visiting around or after the closure date.

How to best experience the Shepherd Gate Clock

  • Best time to visit: Visit during daylight to make out the markings on the clock face and photograph its details. There is no timed performance or scheduled event, so you can stop whenever it fits your Greenwich walk.
  • How long to spend: Allow 5 to 10 minutes to examine the 24-hour dial, read the time and take photographs. If you enjoy the history of science, spend a little longer understanding how this clock helped make Greenwich time accessible to the public.
  • Where it fits in your day: Make the clock a short stop on a walk through Greenwich Park. If the Observatory is open and you have admission, continue into its historic buildings and astronomy displays for a deeper look at the science behind Greenwich Mean Time.
  • Crowd patterns: The clock is a popular photography spot, so other visitors may gather beside the gates. If you want a clearer view of the dial, wait for a gap between groups rather than trying to photograph it through a crowd.
  • What to prioritise if time is short: Focus on the 24-hour dial, particularly the way its hour hand points downwards at noon rather than upwards, as on a conventional 12-hour clock. Then look at the clock's position beside the Observatory gates.
  • Common mistakes to avoid: Don't read the dial as you would a standard 12-hour clock. The clock displays all 24 hours on a single face, so noon and midnight occupy different positions from those on an ordinary clock.

Why it's worth seeing

The Shepherd Gate Clock is more than a historic object on a wall. Installed in 1852, it helped bring Greenwich Mean Time directly to the public through an early electric timekeeping system. Its unusual 24-hour dial makes it easy to distinguish from an ordinary street clock, while its position at the Observatory entrance connects everyday timekeeping with Greenwich's scientific legacy. You can see this small but significant landmark without paying for Observatory admission.

A dial that runs for 24 hours

Unlike most familiar clocks, the Shepherd Gate Clock displays the full day on one dial. Its arrangement is a practical reminder that the history of timekeeping includes systems designed for astronomical observation, not just everyday schedules.

An early public electric clock

The clock formed part of an electrical master-and-slave system, in which a master clock sent signals to other clocks. This helped distribute accurate time beyond the Observatory itself and made standardised time more accessible.

A landmark with protected status

The clock and the wall supporting it received Grade I listed status in 1973. Its position beside the Observatory gates has made it a recognisable Greenwich landmark for generations of visitors.

Historical & cultural significance

The Shepherd Gate Clock began operating on 13 August 1852, making Greenwich Mean Time publicly visible through an electric clock system. It originally displayed astronomical time, with the day counted from noon to noon. After the International Meridian Conference of 1884, it was changed to civil time from 1 January 1885. The clock has continued to show Greenwich Mean Time without switching to British Summer Time, preserving an important link to the history of standardised time.
