Hessisches Landesmuseum (Hessian State Museum)
The museum occupies a grandiose Art Nouveau and neo-renaissance-style building complete with tower, telling the story of the North Hesse region over three floors. The permanent collection ranges from exhibits left by the region's first human inhabitants, to the Middle Ages, to the times of the landgraves, to the present. There's a great view from the top of the tower.
