6. Predjama Castle, Slovenia

Predjama Castle in Slovenia, about an hour south of Ljubljana, might just be one of the most extraordinary castles in the world. This fascinating fortress is built right into the side of a cliff, inside a cave. And if that wasn’t intriguing enough, it was home to the Slovene version of Robin Hood, Erazem Lueger (also known as Erasmus of Lueg), who famously lived and died here. He managed to elude the Holy Roman Emperor for so long thanks to a network of hidden passageways that ran through the cave the castle was built into. Legend has it, he was only defeated—while on the toilet—because of a betrayal.
If this *Game of Thrones*-worthy tale doesn’t compel you to visit, consider that in 1991, treasure was uncovered on the castle grounds. A robber baron, hidden riches, secret passageways, a castle carved into the side of a cliff... Predjama Castle truly lives up to its legendary status.
5. Bled Castle, Slovenia

Lake Bled, nestled in Slovenia, is captivating the world with its breathtaking beauty. The allure is undeniable—its sparkling blue waters, rich history, a resort-like ambiance, a renowned island church, and the majestic castle.

Bled Castle stands tall above the glacial lake, with the striking Julian Alps as a magnificent backdrop. Thought to be the oldest castle in Slovenia, with origins dating back to at least 1011, the castle is now a venue for special events, including weddings and high-level political meetings.

Eger Castle, located in Hungary, is a remarkable historical site that you won’t want to miss.

Eger, a charming town situated in the 'Valley of Beautiful Women' in Hungary, is just a short two-hour train ride from Budapest. Although not widely known outside Hungary, the town and its historic castle are full of fascinating stories and rich heritage, making it a hidden gem worth discovering.
Eger Castle is famously known for the siege of 1552, where the Hungarians successfully repelled the invading Ottomans. This month-long siege, which ended in defeat for the Ottomans, halted their advance for nearly 50 years. According to legend, the Ottomans, upon retreating, spread tales of the Hungarian strength, which they attributed to the Hungarians' tradition of drinking 'bull's blood' to gain extra power and energy. This 'bull's blood' was actually a local red wine, which continues to be called Egri Bikaver to this day.
The castle is just a short walk from the charming square, offering a stunning view over the city and the valley below. After exploring the castle, head to the renowned wine cellars of the valley to taste Egri Bikaver and other local wines straight from the source. It's a new way of experiencing wine—cellar-hopping instead of traditional wine tasting.
