Tuesday's lunch hour tip is the amazing Berlin Philarmonic. A short-duration concert (around an hour) happens every Tuesday at 13h, for free. People make the Philarmonie's foyer full, sitting on the stairs, on the ground and everywhere around. Little advice: bring with you a little cushion for more comfort and try to arrive early to find the good spots.
Rixdorf is definitely my favourite area of Berlin, because it is a historic village within in Berlin. At the moment it is under heavy construction, and I found this strange, nearly taken-down building sitting in the middle of the quaint neighbourhood.
Möckernbrücke is a station of the Berlin U-Bahn network in the western Kreuzberg district, named after a nearby bridge crossing the Landwehrkanal. The bahnhof (train station) is part of the first Stammstrecke route of the Berlin U-Bahn opened on February 15, 1902. As the station also served the nearby Anhalter Bahnhof the original building was soon getting too small to cope with the rising number of passengers. It therefore was demolished and replaced by the current station opened on March 25, 1937. Severely damaged by air raids it was closed on January 30, 1944 and not reopened until June 16, 1947. I like it here for the spookiness and feeling of impending doom that it has on a rainy day.
