The Elbauenpark was carved out of the landscape for a 1999 garden exhibition, and has rose, sculpture and other gardens and a butterfly house. Its most unusual attraction, though, is the conical, 60m-high Jahrtausendturm (Millennial Tower), which bills itself as the world’s tallest wooden tower. Inside is a display on history from ancient times to the present, including a Foucault pendulum. Take tram 5 to Herrenkrug or tram 6 to Messegelände.
