Lake Lohja, my home lake, has an area of 122 km² with 31 km² of islands. It has rich and versatile nature, but also it offers different views to cultural landscape. I went Karstu public beach, which is on the north-west side of the lake. While swimming I spotted Church of St. Lawrence, which is built in the turn of the 15th and 16th centuries, tower of Tytyri limestone mine and Mine Museum, Pitkäniemi industrial area with an old paper mill. A view to the “city”.
