Kew Observatory, Royal observatory in Richmond, England
Kew Observatory is a three-story stone structure with an octagonal central chamber, rusticated ground level, and a rotating dome that crowns the building. The design includes specialized features for astronomical observation and measurement work during the Georgian period.
King George III commissioned this observatory in 1769 to observe the transit of Venus, enabling scientists to calculate the dimensions of the solar system. From 1910 to 1980 it served as a meteorological office, transmitting weather forecasts across the United Kingdom.
The observatory influenced the architectural design of multiple scientific institutions across Britain and Ireland during the Georgian period.
The building is easily visible from the outside and sits in an accessible area of Richmond with good paths nearby. It fits well into a walking tour of the town's historic districts and surrounding green spaces.
The telescope dome is the oldest functioning rotating cupola in the world and retains its original mechanical system from the 1700s. Few visitors realize they are looking at engineering that has operated continuously for more than two centuries without major alterations.
