One of the greatest history museums on the Scandinavian west coast covering ancient Bohus County history from bronze age, iron age, viking age to modern era with its fishing industry - including the herring periods - stone quarry & carving industry, shipbuilding history, architecture history, merchant shipping history as well as key innovation history such as the Laurin Skandia ignition ball engines, also known as Lysekil motor (French "moteur de Lysekil"). The Skandia engines are also shown in a separate museum located a mere 10 minutes walk across the town. The engine may still be experienced in tours organised on the 130 year old tugboat Harry.
