A drawbar slot is a usually square hole in a doorway or window frame into which a drawbar was pushed to secure the door or window (usually) from the inside. They can be found in castles, ecclesiastical buildings and residences from the medieval era to about the Georgian period[1]. The consist of a "resting" slot which can be up to 2m deep and a receiving slot into which the drawbar was pushed to lock the opening. They are not to be confused with putlog holes which were used to hold the beams for scaffolding.
This data is interesting to see which buildings had the defence means of a drawbar.
How to map
If possible, map the entrance=* or in rarer cases window=* and add the drawbar_slot=*. The choice of values are
yeswhen a drawbar slot (pair) is presentdouble/ triplewhen two or three pairs of drawbar slots were present, i.e. when two or three drawbar were in usenoto mark that a location has been surveyed, but no drawbar slot is presentblockedto mark a blocked drawbar slotmaybefor locations where drawbar slots would be expected, but plaster or wooden door frames don't allow for a definitive answer, but the tag shows that a survey has taken place.
If you cannot add the entrance for privacy reasons or because the source is only hearsay, you can add the key drawbar_slot=* with its value to the building. Ideally, an on-site survey will add more details.
If you have access enough to measure the depth, you can add drawbar_slot:depth which is more interesting in combination with width=* for the doorway width.
