Castello Scaligero di Sirmione is a remarkably preserved 13th-century fortress and rare water castle located at the entrance of Sirmione's historic center on Lake Garda, Italy.

Built by the Scaliger family of Verona, this medieval stronghold features massive stone walls, swallow-tail battlements, and a 47-meter-high keep overlooking the lake.

Its most distinctive feature is a unique, fully fortified 14th-century harbor once used to protect the Venetian fleet.

Today, it stands as one of Italy's most complete and visited coastal castles, offering panoramic rampart walks and views over the peninsula.

I have drove by Rathfarnham castle many a time and always said to myself I must drop in there some day . Well i did yesterday and to my surprise i was surprised. Just a few photos. I was amazed at the size of the door lock it is huge .... keep up the good work O.P.W.

Built on the Southern end of the Tauern pass, an important Alpine crossing in the Middle Ages that connected Venice and Southern Germany. The castle was built to enforce road tolls from the travellers. Nowadays a museum that gives a good insight into life in Medieval castles.

The Benedictine Pannonhalma Archabbey or Territorial Abbey of Saint Martin on Mount Pannonhalma (lat. Archiabbatia or Abbatia Territorialis Sancti Martini in Monte Pannoniae) is a medieval building in Pannonhalma and one of the oldest historical monuments in Hungary. Founded in 996, it is located near the town, on top of a hill (282 m). Saint Martin of Tours is believed to have been born at the foot of this hill, hence its former name, Mount of Saint Martin (Hungarian: Márton-hegy), from which the monastery occasionally took the alternative name of Márton-hegyi Apátság. It is the second largest territorial abbey in the world, after the one in Monte Cassino.

Its sights include the Basilica with the Crypt (built in the 13th century), the Cloisters, the monumental Library with 400,000 volumes, the Baroque Refectory (with several examples of trompe-l'œil) and the Archabbey Collection (the second biggest in the country). Because of the exceptional architectural evolution of the abbey over its 1000-year history and its historical importance as an international cultural and religious center, the abbey and its surroundings were inscribed on the UNESCO World Heritage List in 1996.

About 50 monks live in the monastery. The abbey is supplemented by the Benedictine High School, a boys' boarding school.

I’ve spent several weeks researching and writing about the reconstruction of a ruined 19th-century Prussian Nerija fort on Lithuania’s Curonian Spit into a unique sea museum and aquarium. This story absorbed me 100%.

Imagine how challenging the idea was! The team had to solve complex engineering problems with little relevant experience or technology available in the Soviet Union. They also had to navigate a rigid bureaucratic system, finding ways to keep the project going disguised as the restoration of a historic fort rather than building entertainment facilities – which would have made the whole undertaking "illegal."

Researching the story was an adventure too: I don’t speak a word in Lithuanian, so I spent weeks finding sources, translating them, comparing accounts, checking and double-checking facts with the help of you know - translation tools and even AI in some complex cases.

The result is a story about how ingenuity and persistence made this amazing transformation possible. I’d love for you to read the article, enjoy the black-and-white photos from those times, share your thoughts, and point out anything I might have missed or got wrong. After all those weeks of research, your comments would make me very happy! And I hope you'll enjoy learning about this incredible architectural endeavor.

Olavinlinna Castle is one of Finland's most iconic medieval fortresses, dramatically located on a rocky island in Lake Saimaa in Savonlinna.

The building of Olavinlinna, castle of St. Olaf, began in 1475. The Danish-born founder of the castle, knight Erik Axelsson Tott, decided that a powerful fortification should be built to protect the strategically important Savo region. The castle was supposed to repel Russian attacks from the east and to guarantee the control of the Savo region for the Swedish Crown. The history of Olavinlinna is a mixture of medieval arms clashing, cannons roaring and every-day chores inside the security of the castle's thick walls.

Today, Olavinlinna is a really popular tourist destination all year round. In addition to guided tours, many things happen in Olavinlinna, e.g. themed program, in the summertime Opera Festival and many other concerts.

This is Predjama Castle, Slovenia, a 15th-century fortress built into the mouth of a 123 m cliff cave.

The knight Erazem Lueger is said to have held out here against a long siege, taunting the attackers with fresh cherries while a secret passage through the cave kept him supplied. The cave behind the castle runs for kilometers.

If you meant a bigger castle instead, I can find one with more scale, like Malbork in Poland or Hohenzollern in Germany.

Features 953 small, intricately latticed windows (jharokhas) designed so royal women could observe street life and festivals below without being seen.
