Riga City Festival 2011

Riga has just celebrated its 810th birthday with concerts, markets, a knights' tournament, a retro car parade, a salsa marathon, a regatta, aerobatic displays, and many other engaging and crowd-pleasing events. It seems the highlight of this year's celebrations was not the customary fireworks - also impressive enough - but the casting of a key to Riga from 52,763 keys previously donated to a chest.
