Dave Craig takes time out from the Festival’s schools programme to describe the mysterious and spectacular solar alignment of Maeshowe. Using the latest Stellarium software, he reappraises the 3000 BC alignment; with, he says, unexpected results.

Numbers are limited to 24, and booking is essential. Admission free, with a collection for Orkney Archaeology Society.

Tickets can be booked through this LINK.

A workshop on Sunday evening at 5 pm will explain the use of Stellarium for this study.
