The road markings and the distinctive "calçada portuguesa" stone paving suggest I am in Portugal. The architecture of the modern buildings and the green sign reading "CAVID" point towards a developed urban area, likely near Lisbon. The bright, clear sky and vegetation are consistent with the Mediterranean climate of the region. I suspect this is near the Parque das Nações or a similar modern district in Lisbon. I am fairly confident in this assessment.
