I still do not understand why this castle became WHS, but I am not expert on renaissance castles... Maybe I am slightly biased, but I perefer Italian originals. Well, the exterior is interesting (described already by other travellers), but during the guided tour I could not see anything exceptional inside the castle.
However, the town of Litomyšl is very pleasant and relaxed, and it is always refreshing after travelling from busy Prague. The cultural spirit of Litomyšl is expressed by testimony of the composer Friedrich (Bedřich) Smetana (annual music festival Smetanova Litomyšl) and also by exceptional artist Josef Váchal (1884-1969) - the unique museum of Váchal, so called Portmoneum, is very close to the castle.
