The Viirilä Local History Museum showcases the farming and craft culture of Ruotsinpyhtää within the grounds of an old farmstead. The main building dates back to the late 18th century, and the surrounding area offers views of the village’s agricultural landscape. The collection includes approximately 3,000 artifacts that illustrate local daily life and trades. Outside the public season in July, the museum welcomes groups by appointment. Visits in the fall must be arranged in advance with the Loviisa City Museum.
