Wismar is a city in northern Germany, on the Baltic Sea, known for its well-preserved medieval buildings. Interactive exhibits at the World Heritage House explore the city’s history. Constructed around 1600, Wasserkunst is a spring-fed stone well built to supply the city with water. The 1450 brick Wassertor is the only remaining original city gate. The phanTECHNIKUM museum has interactive technology exhibits.
