Fodor's Expert Review Kaiserthermen

This enormous 4th-century bathing palace once housed cold- and hot-water baths and a sports field. Although only the masonry of the Calderium (hot baths) and the vast basements remain, they are enough to give a fair idea of the original splendor and size of the complex. Originally 98 feet high, the walls you see today are just 62 feet high.
