If you have any inquiries regarding the event, please contact the team at info@nisciencefestival.com. Maps & Memories is a 2 year community heritage project that marks 200 years since the first mapping survey began on Divis Mountain by the Ordnance Survey. These early efforts laid the foundations for how we understand land, ownership, identity & geography across the island today – with continued cultural, political & scientific significance.
