Not sure how old the building actually is, but I do know some information about it.The building (and the attached orange one) was used by the nazi's during WW2 as a prison and for interigation. On the right side of the building (from the photo perspective) there is a set of stairs, supposedly one man threw himself off the building and landed on the stairs to get away from the nazi police.
In the attached red/orange building, carvings from people can be found in some locations inside the building from people who were being kept there during WW2, usualy just a name and date.
