About the place

Ulugh Beg, Timur's grandson and ruler of Samarkand, was a working astronomer. On a hill north-east of the city he built a large round observatory, where he and his scholars measured the positions of stars and the length of the year.

After his death the building was destroyed and forgotten. Archaeologists found its site in the early twentieth century, and the surviving part is the curved trench of a huge meridian arc cut into the rock.

A small museum next to the site tells the story of Ulugh Beg and his astronomical tables, which were later studied in Europe.
