Burgstraße is easy to find. Coming from Unter den Linden, head for the Berliner Dom and cross any of the two bridges flanking it from the east (Karl-Liebknecht-Brücke) or from the west (Friedrichsbrücke) connecting the Museumsinsel with the northern bank of the Spree, and there it is. But finding Kleine Burgstraße in Berlin-Mitte might be a bit of a challenge. "‘Kleine’ Burgstraße? Where is that?'“, I hear you ask.
I, your Berlin Companion, am here to help: if you go to Berlin-Mitte and stand on the Karl-Liebknecht-Brücke facing east, then squint your eyes, focus and swiftly travel back in time to 1875, this is what you will see before you instead of the high-rises and the multilane of Karl-Liebknecht-Straße.
In 1887-1888 Kleine Burgstraße was demolished together with Brauhausstraße and Papenstraße to build a magnificent new street that would serve as an extension of Unter den Linden, Kaiser-Wilhelm-Straße.
It is hard to believe that with the Stadtschloß - by 1875 four years into being the seat of the new German Kaiser! - only several hundreds meters away, this is what Berlin looked like in mid-nineteenth century.
