As it stood in 1356
What Kašperk Castle looked like in its prime.
Perched on a narrow rocky ridge, the castle presents a long, continuous grey-stone curtain wall linking a tall rectangular keep with a steep, pyramidal slate roof and a lower secondary tower with a gabled tile roof; the masonry is rough-faced local stone. The silhouette is linear along the ridge, with battlemented wall-tops and a compact inner bailey. Dense conifer forest falls away on the slopes below and the castle looks complete and roofed at its prime.
Its story
The story of Kašperk Castle.
Kašperk was founded in 1356 and is said to be the most highly located royal castle in Bohemia, standing at 886 metres above sea level in the kingdom's forested south-west. Its core is two residential towers linked by an oblong palace, deliberately set back from the outer walls; the tower fronts rise 30 metres without a single opening, save one bay window in the western tower, to make the stronghold harder to storm.
From 1411 to 1454 the castle was in the hands of the house of Zmrzlík of Svojšín and Orlík. In the mid-15th century it passed to the powerful Sternberg family, who held immense sway over the region. Since 1616 Kašperk has been the property of the town of Kašperské Hory, and it stands restored on its narrow rocky ridge above the forest today.
