The Jewels of Southwest Tavastia The southwestern part of Tavastia, along the Loimijoki River, is home to many unique bits and pieces of Finland. These jewels of Southwest Tavastia show themselves as shimmering blue lakes, as whispering old forests, as thriving enterprises, encounters and experiences. The Jewels of Southwest Tavastia presents Forssa, Humppila, Jokioinen, Tammela, and Ypäjä as they are now and as they once were, their nature and everyday life, their events and culture. The magnificent photos by photographer Hannu Laatunen take the readers right into the middle of the action, the best atmosphere, and the greatest moments.
