The Golden Roof is Innsbruck´s greatest tourist attraction, certainly its most characteristic landmark. Built by Archduke Friedrich IV in the early 15th century as the residence of the Tirolean sovereigns, the building was earlier known as "Neuhof", meaning New Court. The Golden Roof is the three-story balcony on this house at the heart of Innsbruck´s Old Town. The late Gothic oriels are capped with 2,600 gold-plated copper tiles. It was constructed for Emperor Maximilian I to serve as a royal box where he could sit in luxury and enjoy tournaments in the square below. Completed at the dawn of the 16th century, the Golden Roof was built in honor of Maximilian´s second marriage, to Bianca Maria Sforza of Milan (Maximilian was a ruler who expanded his territory through marriage, not conquest).
