But years later, when Adolf did rise to power, he built a big memorial on the Odeonsplatz to those Nazis who were killed there after the Beer Hall Putsch. Anyone who entered Odeonsplatz was required to give a good Sieg Heil salute to the memorial. Many who didn't want to give the salute bypassed Odeonsplatz by turning down this lane, Viscardigasse. The golden cobblestones today honor the path of those dissenters. It's basically an antifascist shunpike.
