Armagh Observatory

Armagh Observatory is an astronomical research facility in County Armagh, Northern Ireland, housing historic telescopes within a Georgian building and maintaining research spaces across 14 acres of landscaped grounds. The property blends protected architecture with active scientific operations for ongoing study and measurement.

The facility was founded in 1789 by Archbishop Richard Robinson and soon after began solar observations and sunspot measurements between 1795 and 1797. This early phase of solar study laid the foundation for the long tradition of continuous observation that followed.

The building holds the longest continuous daily climate records in the British Isles, with data stretching back to 1794, reflecting the scientific continuity that defines this place.

The grounds are open Tuesday through Sunday with educational programs, interactive exhibits, and guided tours of the astronomical instruments on offer. Plan time to explore both the indoor spaces and the outdoor areas, and wear comfortable clothing for moving about the property.

Visitors can walk through an interactive model of the Solar System, touch a large meteorite, and see historic instruments up close. These hands-on experiences make astronomy tangible and show how scientists have explored space for centuries.
