Right next to the metro stop ‘Klemensplatz’ - the main drag of this small old district, there was a frenetic street stall opened with no signboard but those huge white stickers in extrabold fonts put onto the window, ‘Berliner Imbiss’ - also a very unfamiliar and interesting thing though, that almost every store including pharmacies, clinics etc., didn’t hang up the signboards but put the stickers onto the windows (except the East Street), and they indeed coordinated with the structures very well, formed an typical European ensemble that have been easily to be found in the numerous movies. Anyways, a child eating the ‘Currywurst mit Pommes’ - a quickly-made steamed, then fried pork sausage cut into slices with French fries - with enthusiasm, looking as if he never minded wetting his chops with ketchup provoked my appetite and so made me line up for it. After Passing by a small old marketplace, a colossal space with a huge, old-established looking main structure and its lots of annexes nestled right next to it, later being become aware of as the Deaconess’s Institute, which has been noted for that Florence Nightingale once studied and its use as a great military hospital during the World War - somehow inspired full of solemnity by its relevance to world history.
