Built in the early 16th century, the Landhaushof was the first Renaissance building in Graz and remains one of the most notable Renaissance buildings in central Europe. The massive structure today takes up an entire city block, but the original building containing a law firm and a chapel was much smaller. The building, which was home to the Styrian Diet, was soon enlarged by expanding into nearby buildings. Due to the expansion over the years, the Landhaushof features several different architectural styles, although great care was taken to blend the varied styles together.
The building today features a main façade with elegant round-arched windows, airy porticoes and a three-story arcaded Italianate courtyard. The Landhaushof has three courtyards altogether, each hosting musical concerts and theater performances during the summer months.
