Mølen in Brunlanes, Larvik is a geopark and Norway's largest beach of rolling stones. It is a part of Vestfoldraet, the terrain left behind after the end of the most recent ice age around 10,000 years ago. Mølen is one of Larvik's most popular tourist attractions. It is home to over a hundred species of rock, including Norway's national stone, Larvikite, which is named from the area. The wind and sea have lashed the landscape of Mølen for thousands of years, and the place takes its name from the Old Norse word "mol", meaning a stone mound or bank of stones.
