may I asked which government sources you are talking about?

BEV says 1652 (which is what I've changed it to): https://maps.bev.gv.at/#/center/13.0366,47.3586/zoom/15.9

basemap says 1651: https://stp.wien.gv.at/basemap/#{"center":[1451942.6645715043,6000602.111015906],"zoom":15.254982501426678,"rotation":0,"layers":"0100000000"}

in anyway it's pretty clear, that 1552 was wrong
