« Children, it is a genius that has brought honor to the German fatherland. »— Frederick the Great, Inscription on the base of the Reiterstandbild Friedrichs des Großen, Berlin, 1851
The story that haunts this land
Your journey through Berlin's history begins in front of the Staatsoper Unter den Linden, a building Frederick the Great had constructed in 1742 by Georg Wenzeslaus von Knobelsdorff. With its initial capacity of 700 seats, this rococo opera house was inaugurated on December 7, 1742, with Johann Adolph Hasse's 'Alceste'. Even after its reopening in 1982 following World War II destruction, its 1,200-seat oval hall retains the spirit of the era. Here, you grasp the king's cultural ambition, which transformed Berlin into an arts capital. This historical monument in Berlin is a key starting point for understanding Mitte's world heritage.
Leaving the opera, you arrive at Bebelplatz, a square created in 1743 also under Frederick the Great's order to house the royal opera. This approximately 3,500 m² area tragically became the site of the Nazi book burning on May 10, 1933, where 20,000 books were torched by university students. In the center, Micha Ullman's underground memorial 'Bibliothek', inaugurated in 1995 and visible through a transparent glass plate, bears witness to this loss. The square, surrounded by baroque buildings dating from the 1770s-1780s, is a powerful reminder of Berlin's tumultuous history and Brandenburg-Berlin's past.
Your path then leads you to the Reiterstandbild Friedrichs des Großen, the equestrian statue of Frederick II. Erected in 1851 by Louis Ferdinand of Prussia and sculpted by Christian Daniel Rauch, this 13.5 m tall work was Germany's first large cast-iron equestrian statue. Inaugurated on May 24, 1851, in the presence of King Frederick William IV, it was damaged in 1945 and restored in 1950. It embodies the monarch's stature and the artistic craftsmanship of the time, a historic Berlin monument that has spanned centuries. An essential exploration to understand Brandenburg's heritage.
Nearby, the Neue Wache, built between 1816 and 1818 by Karl Friedrich Schinkel for Frederick William III's royal guard, illustrates another facet of Prussian history. Transformed into a memorial in 1933, then in 1969 by the GDR for victims of war and fascism, it has been Germany's central memorial to victims of war and dictatorship since 1993, housing Harald Metzkes' sculpture 'Mother with Dead Child' (1939). Its dimensions, 28 m long by 18 m wide, command respect. This edifice, though later than Frederick the Great, represents the continuity of the Prussian royal line and the historical repercussions on the city of Berlin.
Finally, your journey concludes at Gendarmenmarkt, a baroque square developed from 1773 under Frederick the Great, named after the Gens d'Armes dragoon regiment. Surrounded by the German Cathedral (1701-1703) and the French Cathedral (1780-1785), both rebuilt after 1945, it features the statue of Friedrich Schiller in its center, erected in 1871 and measuring 6.85 m. With its 160 m length and 75 m width, this square is a testament to Brandenburg-Berlin's urban planning. This themed circuit in Berlin, listed UNESCO Berlin 1990 and a Berlin WelcomeCard Partner, offers an interactive visit and a GPS scavenger hunt to discover Berlin's history and its monuments. You leave with a deep understanding of the philosopher king's legacy, having discovered what to do in Berlin through its most beautiful sites.
