Setting foot on Donso is like stepping back in time. 

This picturesque Swedish island, part of an archipelago to the west of Gothenburg, is home to 1,400 people, many of whose families have lived here for generations. Apart from the odd truck or van, there are no vehicles. Locals whiz about in electric buggies or on two wheels.

Historically, fishing was the economic lifeblood, and the inhabitants were known for their religious conviction.
