Because of massive renovation work, we do not know much about the original look of the castle. At the northeastern side, there are remnants of probably a walled fortification that may have been developed along the whole core structure. The fortification to protect against cannon attack is one of the best examples of the efforts made in the mid 15th century to protect places in an active way. From 1621 Kumburk was in the possession of Albrecht of Valdštejn. After his death, the castle changed hands several times and then, after 1658, Kumburk was nearly destroyed. In spite of that, nowadays it belongs among our most interesting castles.
