I (Mutabor) had spotted this lost place in the very first day in Halle (picture 18 there). Then I'd got to know, that there since the beginning of the XX century was a typograpy, in the DDR times called "VEB Gravo Druck", which had been working until 1992. Some of its buildings were demolished in 2010.
Then I had visited it for several times and found it quite interesting, also I had picked some old electronic components there.
