The architecture of the modern building and the paved walkway suggest a European setting, likely in a Baltic or Nordic country. The vegetation and the overcast sky are consistent with a temperate climate. The street layout and the style of the paving stones are common in urban areas of Estonia. I suspect this is in Tallinn, Estonia. I am fairly confident in this assessment.

The limestone wall and the specific style of the wooden structure are highly characteristic of the Kadriorg district in Tallinn, Estonia. The lush green trees and the overcast, damp conditions align perfectly with the local environment. I can see a sign in the distance that matches the aesthetic of Estonian public information boards. I am very confident this is near the Kadriorg Park area.
