The day begins early. Stupidly early. Let’s call it stupid o’clock. At Stupid o’clock, everything is kind of quiet. Vienna is just waking up. For that matter, so am I. This also holds true for the driver of the U4 U-Bahn. The Train to Klosterneuburg goes every 30 minutes, and as I get off the train, I can see the S40 pull away from Heiligenstadt station. If the U-Bahn had arrived just 30 seconds sooner, I’d have made it. Bugger it, let’s grab a coffee. I need a coffee. It’s stupid o’clock after all. I sit drinking my coffee outside the station, opposite Karl Marx Hof. Karl Marx Hof is known for being the worlds longest apartment building, stretching a full kilometre and then some. It’ll appear again in a later wander. Today I’m heading just a few minutes north, to the town of Klosterneuburg. As its name somewhat suggests, Klosterneuburg is home to a large cathedral. Its also home to some great little Vineyards and offers great views out over the Danube and Vienna. I’m looking forward to getting there.
