I don't remember any signs of it being the volleyball court when I was there. It more looked like some kind of repairs going on. Please leave this note open for now, I'll try to visit the place again in a few days and to check whether there is a volleyball court.

Overall, that area has a number of improperly mapped stuff. E.g. roads near the gates close to two information boards to the south-west are mapped incorrectly, roads to the south doesn't look in reality like the ones on map, stairs of bridge of Augusta Delgava iela are misplaced and drawn incorrectly.

Probably help of someone more skilled than me is required for surveying this area.
