Some years ago i was working in an office in Berlin-Moabit. Close to the office there was the Armenius Markthalle. I liked the place, though it was quite down-and-out at that time - a lot of space blocked by 'supermarket-boxes', lot of market stalls locked or selling cheap stuff. I went there for lunch regularly, but I did not sketch it at this time. I went back in 2010, where more stalls were locked (See above sketches), but it was announced, that it would give some restart, with a new concept. It reopened as 'Zunfthalle' a while ago and you find a mix of old business (some of it always worked), still the local pensioners chatting or drinking their morning-booze and new attempts (direct vendors of regional producers, delis etc.).
Last year we 'berlin.urbansketchers' had a workshop at an event in another covered market place, the 'Markthalle IX' in Kreuzberg, Eisenbahnstrasse. To my surprise it looked structural similar to Arminius Markthalle. I consulted Wikipedia to learn, that in the 1880ies the Berlin 'Magistrat' built a series of those covered markets to replace outdoor markets for hygienic reasons. Most of these were designed by Hermann Blankenstein. Some of them are still 'active' and serve well as Winter-Skeching-Spots.
Today I did a Sketch in 'Markthalle X' (Armenius-Markthalle) and then took a few trains to Kreuzberg, to directly compare it to #IX
Makthalle IX hosts weekend markets with local vendors and the 'Street Food Thursdays' i will definitely visit soon....
