What were the UAV's attacking in Moscow ????

Two unmanned aerial vehicles attacked Moscow on the morning of July 24, Mayor Sergei Sobyanin said. According to TASS, the wreckage of the first drone was found near house number 17 on Komsomolsky Prospekt.

In order to understand what was nearby, I opened Google Maps, found a place where the debris fell, and a little later I opened RuAssets and began to methodically enter the names of adjacent streets into the search bar. What do you think I found near the crash site 500 meters away?
