Still, buying my first guide to Prague, I could not understand why the castle? Then, when I was at the zoo, I also saw something out of the corner of my eye, but again I was not particularly impressed, a little one. Troy Castle is definitely worth a visit. Exterior view and park around - free. All the beauty of the park is best seen from the church of St. Clary. The castle on the entrance side of the bus stop looks quite modest, you need to turn to the courtyard to see all the beauty of this building.→
