Astronomical Heritage Finder

The Astronomical Heritage Finder is available either as a map or as a list. To narrow down the search results, please use the filters below, including at least one of the four lists (UNESCO, IAU, Portal and PC2S). Learn more about filtering on the HowTo filter page.

AuthorityThe Heritage Finder combines different lists of Astronomical Heritage
Properties on the UNESCO World Heritage List or a National Tentative List Properties on the IAU Outstanding Astronomical Heritage list or the Astronomical Heritage in Danger list Astronomical Heritage case studies directly submitted to the Portal by governmental or academic institutions Places connected to the Sky - submitted by our global community
A serial case study contains sites or objects in multiple locations (nodes) Show all nodes in serial properties Show only the main nodes (those selected to represent the whole series)
Search for words or phrases in all lists selected
Case Sensitive search (slower!) when selected

    RED represents Astronomical Heritage in danger
  • and   and   
The term `Heritage in danger´ is meant to inform the community that conditions prevail which threaten the very characteristics of that heritage (be it astronomical or otherwise), and to encourage corrective action. Armed conflict and war, earthquakes and other natural disasters, pollution, poaching, uncontrolled urbanization and unchecked tourist development pose major problems for heritage, including astronomical heritage. Dangers can be ‘ascertained’, referring to specific and proven imminent threats, or ‘potential’, when there are threats that could have negative effects on the (astronomical) heritage values. Details of the actual dangers for a specific property can be found in the respective entity's description.
