A graphic issued by the University of Birmingham show how lunar calendar’s ‘pits’ at Warren Field discovered in Crathes, Aberdeenshire, are believed to align to phases of the moon over the course of the year, as archaeologists think they have discovered the world’s oldest calendar in the field in Scotland.
Until now the first formal time-measuring devices were thought to have been created in Mesopotamia about 5,000 years ago. The pit alignment near Crathes Castle predates those discoveries by thousands of years, experts say. The Mesolithic monument at Warren Field is said to have been created by hunter-gatherer societies nearly 10,000 years ago
