In the heart of Bohemia, not too far from the bustling city of Prague, I, Charles IV, Holy Roman Emperor and King of Bohemia, had envisioned a majestic fortress that would stand as a testament to the glory and might of our empire. A place that would safeguard our nation's most treasured relics and royal jewels. This vision came to life as the towering Gothic castle, Karlštejn. As I gaze upon its tall ramparts and turrets, the memories flood in. I remember instructing my trusted architect, Master Matthias of Arras, to design a structure that would not only be impenetrable but also aesthetically grand. He certainly did not disappoint. The castle's position atop a hill, overlooking the serene Berounka River, provided both strategic advantage and a serene backdrop. The most precious section of this castle, the Chapel of the Holy Cross, is where we stored the crown jewels and holy relics. This chapel, adorned with semi-precious stones and gold, with frescoes reflecting the celestial realm, was a sanctuary like no other. Entering it always evoked a deep sense of reverence in me. Karlštejn wasn’t just a fortress; it was a symbol. During times of unrest or foreign incursions, its mighty walls stood firm, reflecting the indomitable spirit of the Czech people. While I built many fortresses and structures during my reign, Karlštejn holds a special place in my heart. It is not just stone and mortar; it is a manifestation of a king's dream and the resilience of a nation. As the years went by and I watched from my throne in Prague, the castle became a beacon of hope and pride for our people. It wasn't just the royals and nobles who took pride in it, but every single citizen of our great nation. For they knew, atop that hill, Karlštejn stood watch, guarding the legacy and future of Bohemia.
