Trosky Castle – A beautiful Castle located about 10 km south of Semily, Czech Republic. It is the most famous Castle of Czech Republic. Compared to other defensive structures, scattered throughout Europe, it stands out for its unique location. Masons put it between two basalt columns of natural origin. Even though this work is taken away from them a lot of time and it was worth it. Fortress was terrific, but, alas, not impregnable. In the 17th century it was destroyed Swedish conquerors. Of solid walls remained only ruins. But even they are worth your attention.
