“Welcome to Kihnu. We are not a matriarchy,” says Mare Mätas as she meets me off the ferry. I’ve stepped on to the wild and windswept Kihnu island, which floats in the Gulf of Riga off Estonia’s western coast like a castaway from another time. Just four miles (7km) long and two miles wide, this Baltic outpost is a world unto itself that has long been shielded from the full impact of modernity, a place where motorbikes share the road with horse-drawn carts, and women in bright striped skirts still sing ancient sea songs. But Kihnu is no museum – it’s a living, breathing culture all of its own, proudly cared for by its 700 or so residents.
