The 3 Harbours Art Festival takes place in the three seaside villages of Prestonpans, Port Seton and Cockenzie in East Lothian from the 31 May to 8 June 2008. The Festival celebrates the painting, sculpture, literature and history of this coastal strip, a few miles east of Edinburgh.

There are numerous events every day during the festival including a Gala Day, painting workshops, plays, bus tours and musical performances. The Cockenzie power station is illuminated in the evenings.
I'm looking forward to the 3 Harbours Festival as I haven't managed to attend in previous years.
