The historic "Kaevu Valgam" shipbuilding square, which at one time was crucial to the village of Käsmu, was celebrated with the unveiling of a memorial rock on July 14, 2013. Here, the two-mast ships Toudar (1890/1892), Polaris (1899), Edmund (1900), and Adina (1901) were constructed. In 2010, the Viking ship Aimar was built here in order to revive the shipbuilding tradition in Käsmu.
