Create a photorealistic image of a photograph capturing an aerial view of an old European city. The image shows a top-down bird’s-eye view of a historic city in Central Europe, displaying its urban layout. The cityscape features a variety of tiled rooftops, some with turrets, gables, and other architectural details. Narrow winding streets weave through the city, with some wider roads visible as well. Several town squares and old churches can be seen, along with a single town hall. A winding river flows through the city center, adding to its charm. Small parks and green spaces are scattered throughout. The city is full of life, with bustling shops, people, and various modes of transport. Trams are visible on some streets. The terrain is slightly uneven, with gentle elevation changes. On a hill, a medieval fortress with towers and stone walls stands proudly, overlooking the city. The season is autumn, with trees displaying vibrant yellow, orange, and deep red leaves. The lighting is soft and warm, indicating early evening but not yet twilight. The sun is low on the horizon but remains hidden behind a thin layer of clouds, casting a gentle, diffused glow over the city.
