The road markings and the presence of overhead wires for trolleybuses suggest a Central or Eastern European urban environment. The brutalist, grey concrete architecture is very characteristic of Baltic or former Soviet-influenced cities. The landscape is relatively flat with temperate vegetation. I suspect this is Vilnius, Lithuania, given the specific style of the buildings and infrastructure. I am moderately sure of this location.

The architecture is distinctly brutalist, with the curved concrete structure strongly resembling the National Library of Lithuania in Vilnius. The road markings and trolleybus wires are consistent with urban infrastructure in Lithuania. The surrounding landscape and vegetation align perfectly with the area near the Neris River in Vilnius. I am very confident this is Vilnius, Lithuania.
