When it comes to castles and palaces, the minds of many travellers often wander towards the grand châteaux of France or the dramatic towers of Scotland. Yet Southern Europe boasts its own wealth of hidden gems — enchanting fortresses and palatial retreats that remain delightfully under the radar. Exploring these historic treasures not only offers a glimpse into the region’s rich past but also provides the chance to experience quieter, less-trodden corners of countries renowned for their culture and beauty.

Italy’s Secret Strongholds
Italy is often celebrated for its art, cuisine, and rolling countryside, but its lesser-known castles deserve a spotlight of their own. While tourists flock to Rome and Florence, those embarking on private Italy tours have the opportunity to uncover ancient fortresses tucked away in the hills and valleys.
Take Rocca Calascio in the Abruzzo region, for example. Perched high in the Apennines, this medieval stronghold offers sweeping views and a haunting atmosphere that’s utterly unforgettable. Its crumbling walls and isolated location made it the perfect backdrop for classic films like Ladyhawke. Another hidden treasure is Castello di Brolio in Tuscany, a beautiful castle surrounded by Chianti vineyards, where visitors can combine history with some of Italy’s finest wine tasting experiences.
By choosing bespoke tours, travellers can access these remote sites with expert guides, avoiding the crowds and discovering the stories that shaped Italy’s complex history.

Portugal’s Forgotten Palaces
While Lisbon and Porto draw the lion’s share of visitors, Portugal’s countryside hides a tapestry of palaces and castles waiting to be explored. Booking Portugal travel packages that include off-the-beaten-path destinations is the ideal way to unearth these hidden gems.
One such treasure is the Castle of Marvão, sitting atop a steep escarpment near the Spanish border. Its walls seem to grow out of the granite cliffs, offering breathtaking views over the Alentejo plains. In the north, the fairytale castle of Santa Maria da Feira, with its dramatic towers and ramparts, transports visitors back to the days of medieval jousts and feudal battles.
Travelling beyond the typical tourist trail in Portugal reveals a quieter, more authentic side of the country — where ancient stones whisper stories of conquests, kings, and intrigue.
Spain’s Overlooked Fortresses
Spain’s reputation for grand castles often centres around popular sites like the Alhambra in Granada. However, venture off the main routes, and you’ll find dozens of remarkable, lesser-known fortresses that tell equally fascinating tales.
Located in Aragon, the Castle of Loarre stands as one of Europe’s earliest and most impressive examples of Romanesque architecture. Its dramatic location, perched above a rugged landscape, makes it feel like something from a fantasy novel. Similarly, the Alcazaba of Almería offers stunning views of the Mediterranean and a fascinating mix of Moorish and Christian architectural styles.
Spain’s diverse regions each bring their own flavour to castle-building, from the fortified hill towns of Andalusia to the fairytale turrets of Catalonia, making it a treasure trove for castle enthusiasts willing to step away from the usual crowds.
Croatia’s Coastal Castles
Croatia, with its sun-kissed coastline and historic towns, is home to a number of remarkable castles and fortresses that many visitors overlook. Beyond Dubrovnik’s famous walls lies a landscape dotted with impressive strongholds.
The Trakošćan Castle, located in the northern region of Hrvatsko Zagorje, is a picture-perfect 13th-century castle surrounded by forests and a reflective lake. It feels as if it were lifted straight from the pages of a storybook. Closer to the coast, the Klis Fortress near Split offers breathtaking views over the Dalmatian coastline and carries a rich history as a strategic stronghold during medieval battles — and more recently, as a filming location for Game of Thrones.
Exploring Croatia’s hidden castles reveals a country where history and legend intertwine against some of Europe’s most stunning backdrops.
Slovenia’s Secret Castles
Tucked between Italy, Austria, and Croatia, Slovenia might be small, but it boasts an impressive collection of castles, many of which remain blissfully undiscovered by mass tourism.
Predjama Castle, dramatically built into the mouth of a cave, is one of Slovenia’s most fascinating sites. Its unique setting and the legends surrounding its most famous resident, the knight Erazem of Predjama, capture the imagination. Further inland, Bled Castle overlooks the famous Lake Bled, its medieval towers providing the perfect vantage point for gazing over the serene waters below.
Slovenia’s castles blend natural beauty and medieval charm, offering an enchanting experience for those seeking something different from the standard European itinerary.
Tips for Visiting Hidden Castles
- Hire a local guide: Many of these off-the-beaten-path sites offer richer experiences when explored with someone knowledgeable about their history and legends.
- Check accessibility: Some castles are remote or situated on steep hills; sturdy footwear and a reasonable level of fitness are often required.
- Visit during weekdays: Even less-visited sites can become busier on weekends, so plan midweek visits where possible for the most peaceful experience.
- Respect the heritage: Many of these sites are fragile and preserved with limited resources — taking care and following posted guidelines helps protect them for future generations.
Why Choose Off-the-Beaten-Path Castles?
While iconic sites undoubtedly have their place on any travel itinerary, there’s a special kind of magic in discovering somewhere fewer people have tread. Hidden castles often offer a more intimate experience, free from crowds and bustling tour groups. They allow you to step into the past in a setting that feels genuinely untouched, where every stone has a story and every view is yours alone to savour.
Moreover, visiting these lesser-known treasures supports local communities and helps spread the benefits of tourism more widely, ensuring that these historic sites are preserved and appreciated for generations to come.
Conclusion
Southern Europe’s hidden castles and palaces offer something truly special for adventurous travellers — a chance to see beyond the familiar and delve deeper into the region’s fascinating history and culture. From exploring an abandoned stronghold in Portugal to enjoying wine by a Tuscan castle or gazing out from ancient battlements in Spain, these hidden gems promise unforgettable memories and tales to share long after your travels end.
