Kassel's grand town hall, fronted by two striking golden lions, was inaugurated in 1909, with the front section largely rebuilt after the war. On the square in front of the building, strange gutters in the pavement form the Aschrott-Brunnen memorial. In 1908 the successful Jewish industrial Sigmund Aschrott donated a monumental 12-metre-high fountain to the city; Nazi activists destroyed it in 1939. Local artist Horst Hoheisel recreated it upside down and in negative in 1987; people peering down the 12-metre deep hole with water tumbling into it are encouraged to think about what was once here and why it disappeared.
