Just a short boat ride from Nagu lies the island of Seili, a natural gem with a grim past. Once used as a hospital for people with leprosy and then later as the nation’s first public mental health facility, the island still bears traces of this tragic time. Visit Seili to experience the island’s breathtaking beauty and learn more about its bleak history. You will find a museum, restaurant, and guest harbour here as well as a variety of accommodation options.
