Perched majestically above the lush green hills of the Czech Republic, Karlštejn Castle is a gem that has fascinated visitors for centuries. Founded in 1348 by Charles IV, the King of Bohemia and Holy Roman Emperor, this castle was originally intended as his private residence and a secure place for his prized possessions: the royal treasures, including collections of holy relics and the Imperial Crown Jewels. In 1355, Charles IV made his first stay here, immersing himself in the construction and decoration, particularly within the chapels. By 1365, the castle was fully completed with the consecration of the Chapel of the Holy Cross in the Great Tower. Throughout its storied history, Karlštejn Castle has remained in the hands of royalty or state institutions, never passing into private ownership. Today, it is proudly owned by the state. One of the castle's most remarkable features is its original stair arrangement that has been meticulously preserved. Starting from the lower section, you can wander through a small courtyard by the Well Tower and the Burgrave's House before ascending through the grand five-story Imperial Palace and the Marian Tower. At the very top, the castle's architecture culminates with the monumental 60-meter-high Great Tower, complete with its formidable fortifications. As you explore, you'll find the exquisite 14th-century wall decorations, a collection of 129 paintings by Master Theodoric in the Chapel of the Holy Cross. This chapel holds the distinction of being the largest of its kind in the world. The castle also boasts the largest portrait gallery of the Bohemian kings in the Czech Republic, as well as a replica of the royal Crown of Bohemia. Don't miss the unique castle well, a feat of medieval engineering. Adding to its allure, Karlštejn Castle served as the backdrop for the beloved comedy play "Night at Karlštejn Castle" by Czech poet Jaroslav Vrchlický. For those venturing to this historical marvel, the nearby village of Karlštejn offers charming cafes and quaint shops, perfect for savoring a cup of coffee or picking up a local souvenir. The surrounding landscape invites leisurely hikes and picnics, providing stunning views of the castle from various perspectives.
