Austria's second-largest city has a beautiful centre with lots of interesting sites (the Zeughaus has the world's largest medieval armoury), but without the hordes of tourists that crowd Vienna or Salzburg. There are buildings from several epochs, which can be seen from above from the Uhrturm (clock tower), the city's landmark. The site was recently expanded to include Eggenberg Palace, a very pretty late-Renaissance building a short tram ride from the centre. It has a large garden with an interesting archaeology museum, and is certainly a worthy addition to the site.
