The elegant baroque square got its name from Frederick William’s Gens d’Armes cavalry regiment, which had a guardhouse and set of stables for their horses here until 1782. By the end of World War II, the square had been reduced to a pile of rubble and remained in ruins until the late 1970s, when East Berlin began to rebuild.
Anchoring the square are dazzling feats of architecture like the twin cathedrals German Dome (Deutscher Dom) and French Dome (Französischer Dom), whose design was inspired by Rome’s Piazza del Popolo and Friedrich Schinkel’s imposing, neoclassical theater. Travelers have many options to explore the square, on their own or as part of half-day, full-day, group or private tours on foot or by hop on/hop off bus, limousine, boat, or bike.
