Historic observatories are places of awe and discovery where modern astronomy was born, and humankind’s understanding of the physical universe emerged.
The Alliance of Historic Observatories (AHO) acts as a vehicle for global collaboration in research, inspiration and engagement, and preservation of historical resources.
Develop strategies for preserving and sharing our legacies with future generations.
Share methods to preserve the infrastructure of historic observatories.
Tell our stories as a model for how the observatories inspire people around the world to foster greater literacy in science.
Become model institutions of youth STEM programs.
AHO was organized in 2019, and established as a formal entity in 2023.
AHO members engage in various joint activities aligned with alliance objectives: astronomical site, asset, and data preservation; collaborative public engagement and media projects; STEM-focused outreach; and strategic collaboration on mature facility operations.
To nominate an institution or individual for membership, please use our contact form.
AHO observatories meet every fall, typically for a couple of days, to discuss and plan alliance matters, exchange ideas, share experiences, and celebrate the achievements of our members. Vatican Observatory hosted the latest meeting in October 2024. Click here for more details.
Several of our facilities have virtual tours in video or interactive form. Below are links to these media:
