The Edinburgh International Festival (EIF) launched last night with Deep Time, a spectacular light and animation show, which was projected on to the side of Edinburgh Castle.
Thousands of spectators packed into Castle Terrace for the 20-minute display, developed by Tony-Award winning 59 Productions with academics from Edinburgh University.
Edinburgh Castle and its rocky foundation acted as a vast canvas for digitally animated projections charting 350 million years of the deep geological history of the unique location.
The free, ticketed event was played to a specially-composed soundtrack by Scottish band Mogwai and marked the start of a three-year partnership between EIF and sponsor Standard Life.
The show is one of the largest architectural mapping projects created by 59 Productions who worked on the London 2012 Olympic opening ceremony.
It follows last year’s curtain-raiser, The Harmonium Project, which attracted thousands of festival-goers onto Lothian Road to see the transformation of the Usher Hall.
The event required 15km of cabling and 42 projectors.
