„Komisarjat” is an obsolete name for Polish word „Komisariat”, meaning ‘Police station’
In a house located at Wielicka 29 street…. no, there never was any Police Station.
The name of the cache is inspired by pre-war postal address plates, called “mortgage-address plates” those times.
Usage of putting mortgage numbers on address plates had started in late XVIII century. To facilitate collecting the ell-tax*, established in 1784, each Warsaw estate was given its own number (later they became a base for current mortgage numbers).
At the beginning those numbers were used the same way as addresses and personal registration data are used nowadays. But soon people realized that is not very convenient to use only numbering, which is not related in any way to the street name.
This is why in 1868 additional numbering, straightly related to the street names, was introduced. Those numbers were named “police numbers”, going up (depending on the street direction) downstream Vistula River or out from it.
Then you could saw on the buildings address plates containing both, police and mortgage numbers together with the name of building owner and police district (called “Komisarjat”) responsible for the area where a building was located.
Few of them remained till now. Most were destroyed during the WW II or subsequent “renovation” in communist times.
According to data visible on the address plate, fixed just above its modern equivalent,
house at Wielicka street was located within XVI police district area, its mortgage number was 212, and police number – 29. Unfortunately the name of the owner is unreadable.
Archaic name “Komisarjat” is pointing out that the plate was installed on the building in 1936 at the latest, before an ortography reform changed spelling of letter “j” to “i” in that word.
The Second time boundary is year 1916, when due to the administration reform the “Great Warsaw”, containing also Mokotów area, was created (the City was enlarged four times, from about 3 up to 12 thousands hectares). The number of police districts raised from existing 15 to 26, including district XVI, responsible also for Wielicka street.
The cache contains logbook, pencil and few small things for trade.
Beware of the security guys from the building opposite the street.
