Hi!
After a number of difficulties and unexpected setbacks[1] I am happy to
announce that geospatial search for Wikidata Query Service is now
deployed and functional. You can now search for items within certain
radius of a point and within a box defined by two points - more detailed
instructions are in the User Manual[2]. See also query examples[3] such
as "airports within 100km of Berlin":

There are still a couple of things to complete, namely sorting by
distance (coming soon) and units support (maybe). Overall progress of
the task is tracked by T133566[4].
