Leo von Klenze (1784–1864) ranks as one of the most outstanding architects of the 19th century, in a line with luminaries such as Karl Friedrich Schinkel. Serving as the court architect of Maximilian I Joseph of Bavaria and Ludwig I of Bavaria as well as heading the highest planning authority, he left his indelible mark on the cityscape of the "New Munich" and Bavarian architecture in the form of spectacular monumental structures. As popular as Klenze's classicist architecture may appear today, it was not uncontroversial and appeared out of place to locals, newcomers, and tourists. This architectural guide sharpens the artistic minds of viewers with its vivid and detailed descriptions of Klenze's maverick building designs and the historical context of his works. This publication also elucidates central aspects of his theory of architecture and a number of his programmatic paintings. On the occasion of the 150th anniversary of Klenze's death, Adrian von Buttlar's pithy, lucid presentation reminds us of the history and significance of this unique architectural heritage.
