I see a modern, well-maintained urban basketball court surrounded by a wire fence. The architecture of the building in the background looks European, with a classic, stately design typical of cities in Central or Eastern Europe. The lush green trees suggest a temperate climate during the summer months. I suspect this is in a major city, possibly in Poland or Germany, given the style of the court and the surrounding urban layout. I am somewhat confident about the general region.

then: forward

The architecture in the background, specifically the grand, multi-story building with a tiled roof, strongly suggests a Central European city like Vienna or Budapest. The basketball court design and the surrounding park-like setting are common in urban areas throughout Austria. The sunlight and vegetation indicate a pleasant, temperate summer day. I am fairly certain this is in Vienna, Austria, near a central district.
