The Tower Hill Sundial is a unique, ground-level horizontal dial located just outside the Tower Hill Underground Station in London. Functioning as both a functional timekeeper and an intricate pictorial history book, the monument details nearly 2,000 years of the city's past.
Commissioned by London Underground Ltd, the site was unveiled on August 3, 1992, transforming an empty plaza space into a designated public garden and seating area. The space was envisioned by landscape architect John Chitty, who conceived the idea of a giant sundial at its centre, while the renowned English sculptor Edwin Russell was commissioned to bring the historical reliefs to life. Today, the gardens serve as a circular, raised viewing platform overlooking the Tower of London, where tour groups regularly convene to take in the history over the road.
Design and Historical Highlights
At the centre of the dial, just below the large gnomon, sits a prominent bronze anchor, a nod to the dial's close proximity to the River Thames and the historic Pool of London. Radiating outward from this centre is a 3.7 metre (12.14 feet) high bronze band circumscribed by detailed high-relief sculptures.
This outer ring winds chronologically through the history of London and its transport system, stretching from the founding of the Roman city of Londinium in AD 43 right through to the completion of the Thames Barrier in 1982. The reliefs depict iconic milestones, including the construction of Shakespeare's Globe Theatre, the early omnibus services, and the devastating impacts of the Great Fire and the Blitz.
