Archaeoastronomy

… is the study of beliefs and practices relating to the sky in the past, especially in prehistory, and the uses to which people's know- ledge of the skies was put.

Chankillo is inscribed on the World Heritage List

The prehistoric solar observatory and ceremonial centre at Chankillo in Peru, including its famous thirteen towers, has been inscribed on the World Heritage List at the 44th (2021) session of the World Heritage Committee, currently being held in Fuzhou, China, and on-line.

Chankillo’s extraordinary and quite unique monumental solar calendrical device has been recognised as World Heritage just 14 years after Ivan Ghezzi’s and my article “Chankillo: A 2300-Year-Old Solar Observatory in Coastal Peru” was first published in Science (315 (2007), 1239–1243).

According to UNESCO, Chankillo solar observatory is “an outstanding example of ancient landscape timekeeping, a practice of ancient civilizations worldwide, which used visible natural or cultural features. Incorporated in the Thirteen Towers, it permitted the time of year to be accurately determined not just on one date but throughout the seasonal year. Unlike architectural alignments upon a single astronomical target found at many ancient sites around the world, the line of towers spans the entire annual solar rising and setting arcs as viewed, respectively, from two distinct observing points, one of which is still clearly visible above ground. The astronomical facilities at Chankillo represent a masterpiece of human creative genius.” — CR

Two new astronomical World Heritage Sites

Two very different places linked to astronomy have been inscribed on UNESCO’s World Heritage List at the 2019 World Heritage Committee in Azerbaijan. Jodrell Bank Observatory in the UK is the first 20th-century astronomical observatory to become a World Heritage Site, while Risco Caído and the sacred mountains of Gran Canaria is a “cultural landscape” highlighting cultural astronomy operating in a rich historical and social context.

For more information on the two sites see the Portal to the Heritage of Astronomy and for more information on the context of the two successful nominations see the article “Beyond Jodrell Bank: astronomical heritage”.

The picture shows the front covers of the nomination dossiers for the two new World Heritage Sites.
