Hamburg is noted for several festivals and regular events. Some of them are street festivals, such as the gay pride Christopher Street Day festival or the Alster fair, held at the Binnenalster. The Hamburger DOM is northern Germany's biggest fun fair, held three times a year. Hafengeburtstag is a funfair to honour the birthday of the port of Hamburg with a party and a ship parade. The biker's service in Saint Michael's Church attracts tens of thousands of bikers. Christmas markets in December are held at the Hamburg Rathaus square, among other places. The long night of museums offers one entrance fee for about 40 museums until midnight. The sixth Festival of Cultures was held in September 2008, celebrating multi-cultural life. The Filmfest Hamburg — a film festival originating from the 1950s Film Days (German: Film Tage) — presents a wide range of films. The Hamburg Messe and Congress offers a venue for trade shows, such hanseboot, an international boat show, or Du und deine Welt, a large consumer products show. Regular sports events—some open to pro and amateur participants—are the cycling competition Vattenfall Cyclassics, the Hamburg Marathon, the biggest marathon in Germany after Berlin, the tennis tournament Hamburg Masters and equestrian events like the Deutsches Derby. Since 2007, Hamburg has the Dockville music and art festival. It takes place every year in summer in Wilhelmsburg.
