Zog turns 15

Since Zog first burst onto the scene in 2010, he’s captured imaginations around the world. Written by Julia Donaldson, former UK Children’s Laureate, and brought to life with Axel Scheffler’s iconic illustrations, the tale of perseverance, friendship (and a few fiery mishaps!) has become a bedtime favourite.

Celebrating 350 Years of Innovation and Exploration

In 1675, King Charles II commissioned the Royal Observatory at Greenwich, unknowingly setting in motion centuries of astronomical discovery, navigational breakthroughs and global timekeeping.

Greenwich is where East meets West, and home to the Prime Meridian – an invisible line that runs through the very ground. The Royal Observatory is where Greenwich Mean Time was born, and it’s been guiding explorers, scientists and seafarers ever since.

Now, 350 years on, this iconic institution has been honoured on a UK £2 coin.

A Design Packed with Symbolism

Created by renowned designer Henry Gray, the reverse design of the 2025 Royal Greenwich Observatory £2 is a treasure trove for collectors.

Here’s what you’ll spot:

  • The Shepherd Gate Clock – one of the world’s first public displays of Greenwich Mean Time.
  • Ursa Minor and Polaris – the constellation and star used for celestial navigation across centuries.
  • The Prime Meridian on a globe – marking the division between East and West.
  • And along the edge, the words: “PERFECTING THE ART OF NAVIGATION” – a phrase taken from the Observatory’s founding Royal Warrant.

Every detail speaks to the Observatory’s unmatched contribution to science, timekeeping, and navigation.

The £5 Coin Celebrating 350 Years of the Royal Observatory Greenwich

The Royal Observatory Greenwich is one of Britain’s greatest scientific landmarks. Established in 1675, it became the cornerstone for global navigation and timekeeping. And now, this remarkable legacy is captured in an equally remarkable £5 coin — a design that pays tribute to centuries of exploration, astronomy, and engineering.

Whether you’re a passionate numismatist or simply intrigued by the wonders of science, this coin is worth a closer look.


A Landmark in British Coin Design

At first glance, this isn’t just a commemorative piece — it’s a statement of precision. The design is deeply symbolic, dividing the surface into two distinct yet interconnected halves.

Running vertically through the centre is the Prime Meridian, the global reference point for time and space, originating at Greenwich. This bold line doesn’t just split the coin — it connects hemispheres and disciplines.

East: Gazing Upwards

On one side, the emphasis is celestial. The Great Equatorial Telescope dome of the Royal Observatory rises beneath a starry sky, where Ursa Minor and the North Star remind us of centuries of cosmic observation and navigation.

West: Mastering Time

Opposite, the design moves from stars to seconds. Intricate mechanisms represent Clock B, a pioneering free-swinging pendulum clock by Martin Burgess, renowned for its unmatched accuracy. It’s a tribute to human ingenuity — where measuring time became an art and a science.
