About 500 cyclists have ridden naked through the streets of Berlin, passing the German parliament, the Bundestag, on a journey to promote nudism as a lifestyle choice.
The ride started in Mauerpark in east Berlin, close to the former border, and then headed to the government quarter.
Participants enjoyed the sun on their backs with temperatures reaching 30 degrees Celsius
Organisers said the more than 30km route was to follow the Berlin Wall Trail to Schonefeld, which is near the airport.
Organisers said the event celebrated diversity of human bodies.
The aim was to send a signal of "tolerance and self-acceptance, closeness to nature and protection of the environment and for inclusion and diversity".
Participants had the choice of being partially or completely naked, organisers said.
The organised nudist movement has lost followers in Germany in recent decades.
In the 1990s the German Naturist Federation had 65,000 members; now it has 34,000.
