From the soaring Octagon of Ely Cathedral to the proportions of the city’s historic streets, discover how mathematics, faith, and craftsmanship shaped Ely’s remarkable buildings.

This guided walk explores the history, design, and symbolism found within some of Ely’s most striking architecture, revealing how medieval builders used geometry, proportion, and careful planning to create harmony, balance, and beauty — principles that later builders continued to reinterpret through the 17th century, the Victorian revival of medieval styles, and even in modern architecture.

This leisurely 90 minute walk commences from Oliver Cromwell’sm House.
