The road markings and the blue directional signage with the word "HOLEŠOVICE" strongly point toward the Czech Republic. The driving side is on the right, which is consistent with Central Europe. The architecture of the concrete and brick tunnel entrance looks typical of urban infrastructure in Prague. I am fairly confident this is in Prague, specifically near the Holešovice district.

The blue road signs are clearly Czech, confirming the location. The tunnel entrance and the specific red brick retaining wall are characteristic of the Blanka Tunnel complex in Prague. The sign mentioning "Holešovice" confirms I am in the northern part of the city. I am very sure this is in Prague, Czech Republic.
