Bavaria's greatest monarch, Ludwig I, was responsible for Munich in the 19th century becoming known as Athens on the Isar, and the impressive buildings designed by Leo von Klenze that line this elegant and expansive square bear testament to his obsession with antiquity. The two temple-like structures facing one another are now the Staatliche Antikensammlungen (an acclaimed collection of Greek and Roman antiquities) and the Glyptothek (a fine collection of Greek and Roman statues). After WWII, Munich authorities ensured that the square returned to the more dignified appearance intended by Ludwig I, since this was a favorite parade ground for the Nazis, and it was paved over for that purpose in the 1930s. Today, the broad green lawns in front of the museums attract students and tourists in the warmer months, who gather for concerts, films, and other events.The area around here, focused on Briennerstrasse, became the national center of the Nazi Party in the 1930s and '40s,
with various buildings taken over or built by the authorities. Nazi HQ, the Brown House, was between Königsplatz and the obelisk at Karolinenplatz. Destroyed in the war, the new Munich Documentation Centre for the History of National Socialism opened here in 2015 on Brienner Strasse 34. On Arcisstrasse 12 is the Nazi-era building (now a music school) where in 1938 Britain's prime minister, Neville Chamberlain, infamously thought he had negotiated "peace in our time" with Hitler.
