It is a must see in Rieka! It has it all - good history and great wives over Rieka.
Sightseeing isn't very long, but if you want to be thorough it can take you up to 1-1,5 h. You can learn about the castle history, and about a history of castle renovation. Also you can climb up to the tallest tower (not difficult) and watch great panorama of a city.
In plus - there is a tourist office in the castle, where is very nice and helpful staff, that will tell you all you need to know about castle and Rieka. And it isn't on a maps!!! Also free toilets.
In minus - movie about castle isn't very good. But the place, that the movie is shown is awesome 🙂
