The Litomysl Castle is on my penultimate day of Czechia WHS circuit.  I am not going to add much to the comments already posted except for my experience, or lack thereof during the visit. 

1) the site is under renovation so the side of the castle is covered by scaffolding and screening. The Sgrafiti are therefore not visible from the entrance side. The other side with the lawn is enclosed by construction fencing, thus you can’t get a photo.  I was lucky to sneak in for a few photos when the construction crew was changing shifts and opened the gate. 

2) Inside the courtyard, they are building a music performance platform therefore obscuring the sgrafiti inside. 

3) There was no English language guided tour or self guided tours for the interior rooms. 

4) The room that was supposed to explain “Why Litomysl became a UNESCO WHS in English “ had only Czech language displays.
