here, by the light of candles, local artists decked out in historic costumes perform morzart's most famous works. you'll find mozart memorabilia and lots more on getreidegasse, salzburg's most popular shopping street. high, narrow houses tightly huddled together give the road a certain architectural elegance. iron guild signs announce enticing storefronts, and every passageway holds shops selling jewelry, traditional clothing, and antiques. the street developed downstream from a former merchant settlement on the waagplatz, or "weighing square." the houses appear to be quite narrow, but actually they extend far back in depth. because of the terrain, the builders could expand only upwards. across the river from getreidegasse, you'll find the loveliest gardens in salzburg. an extravaganza of flowerbeds, fountains, and statues make a glorious pedestal for mirabell palace. remember wolf dietrich, the archbishop who built the residenz? well, in the early 17th century, he built mirabell palace as a luxurious private home for his mistress. she lived there along with at least 10 of their children.
