The Church of the Annunciation of the Virgin Mary at Trávníček, Na Slupi, Vyšehrad, Praha 2, Allegedly the first Gothic church in Prague founded as Gothic from beginning.
The biggest problem for photography in Prague is transportation - tramway, tram wires, traffic lights, signs, railings ... (If you do not fix /edit it/ a photo like me.)
But it's a low price. Charles IV built the city so modernly that on its original ground plan it could withstand all traffic even after nearly 700 years!
Few buildings only had to break down.Prague is not a scansen, but a living city!
