Like all architectural styles, the Neo-Renaissance did not appear overnight fully formed but evolved slowly. One of the first signs of its emergence was the Würzburg Women's Prison, which was erected in 1809 designed by Peter Speeth. It included a heavily rusticated ground floor, alleviated by one semicircular arch, with a curious Egyptian style miniature portico above, high above this were a sequence of six tall arched windows and above these just beneath the slightly projecting roof were the small windows of the upper floor. This building foreshadows similar effects in the work of the American architect Henry Hobson Richardson whose work in the Neo-Renaissance style was popular in the USA during the 1880s. Richardson's style at the end or the revival era was a severe mix of both Romanesque and Renaissance features. This was exemplified by his "Marshall Field Warehouse" in Chicago (completed in 1887, now demolished). Neo-Renaissance was adopted early in Munich, often based directly on Italian Palazzi, first appearing in the Palais Leuchtenberg (1817–21), by Leo von Klenze, then adopted as a state style under the reign of Ludwig I of Bavaria for such landmarks as the Alte Pinakothek (1826–36), the Konigbau wing of the Munich Residenz (1825–35), and the Bavarian State Library (1831–43).
