In the old city, it is pointless to single out something separately, since it is necessary to feel it completely, to indulge in a single spirit and absorb the surrounding with all the senses. Appreciate the city, the most functional, for the life of a city dweller of the 18-19th centuries, currently performing a single function (but how!) - tourist. If once you are imbued with the charm of Prague, then, I think, do not lose this feeling in the future. Visit often in beautiful places!
Prague's Old Town is a mix of different historical periods. The Old Town Square with the old town hall and the Tyn Church are certainly an architectural highlight. In particular, the view from the city hall on the illuminated building in the evening is definitely recommended.
