Full case studies

Full case studies, structured as sections of draft dossiers, aim to highlight issues that might arise if State Parties were to prepare nomination dossiers highlighting the astronomical values of the properties concerned. Examples:

Chankillo, Peru

Risco Caído and the sacred mountains of Gran Canaria, Spain

Short case studies

Short case studies follow the format used in the ICOMOS–IAU Thematic Study on Astronomical Heritage. Examples:

Hortobágy Puszta, Hungary

Jantar Mantar at Jaipur, India

Sydney Observatory, Australia

Movable objects

We have recently introduced movable object case studies in order to document items such as artefacts and portable instruments in a more suitable format. Examples:

Nebra Sky Disc, Germany

Ishango Bone, Democratic Republic of the Congo

IAU “Outstanding Astronomical Heritage” sites

The IAU has begun to compile its own list of astronomical heritage sites that are outstanding in the history of astronomy but are not necessarily suitable for inscription on the World Heritage List. The period from the European Renaissance to the middle of the 20th century was an extremely rich one for the history of astronomy and the initial list focuses on sites of this type. Examples:

Uraniborg and Stellaeburgum, Sweden

La Plata Observatory, Argentina
