This is Austria. Castles can be seen all over the mountains! They are formidable, striking, virtually unbeatable, and impenetrable. In fact, some of the castles were constructed so firmly that the only way for invaders to seize control of them was by starving the people until they gave up.

Austria also has magnificent castles that resemble scenes from a fairy tale. Soldiers could see over the valleys to check if any intruders were approaching because they were typically positioned atop the tallest hills in the region. Nestled amidst a verdant woodland, the castles are visibly distinct. The castles are visible for kilometres around due to their immense size and white or light-colored stone construction.

1. Burg Clam: All of Upper Austria belonged to Otto von Machland, who constructed Burg Clam in 1149. It was a stronghold with two towers at the time. To protect the castle during the thirty-year conflict, the Clam family maintained a private army. Clam was frequently besieged, but no enemy forces were ever able to take the castle.
    
2. Burg Neuhaus: From the bottom of the valley, Neuhaus Castle is hardly visible; the tower soars into the sky. When the castle was first recorded in the 13th century, it was most likely built as a frontier fortress to protect the Tyrol Counts from the Bolzano Counts.
    
3. Herberstein Castle: Herberstein Castle appears to be a scene from a fairy tale, perched atop a precipitous cliff above the Feistritz ravine. The even higher environs' woods conceal the castle from plain sight, providing natural defence against intruders. The 700-year-old building blends three architectural eras: Baroque, Renaissance, and Gothic. The Gironcoli Museum, the ancient gardens, the zoo, and guided tours of a portion of the castle are all included in the admission price.
    
4. Liechtenstein Castle: Situated on the southern boundary of the Vienna Woods, Lower Austria is home to the Liechtenstein Castle. The fortress, which was first constructed in the twelfth century, was devastated twice by the Ottomans in 1529 and 1683, and it lay in ruins until it was reconstructed in the nineteenth century. This castle served as the filming location for a segment of the 1990s rendition of "Three Musketeers."
    
5. Burgruine Gallenstein: Burgruined Situated in the Austrian state of Carinthia lies the mediaeval castle known as Gallenstein. Originally built in 1278, Gallenstein Castle was a stronghold that was never overrun. Only the ruins of now stand, yet with their striking walls and towers, they give tourists a window into the past. The public can explore the castle ruins, which provide breathtaking views of the surroundings.
    
6. Kreuzenstein Castle: Situated on a forested mountaintop with a view of the nearby settlement of Leobendorf, the Kreuzenstein Castle is close to Vienna. In actuality, the existing building is a 19th-century architectural dream assembled from fragments of mediaeval constructions from throughout Europe. Built between 1879 and 1908 on the site of a previously demolished castle, the massive building was constructed by Count Nepomuk Wilczek to hold his collection of armour and late-Gothic art pieces.
    
7. Hohenwerfen Castle: Hohenwerfen Castle is an amazing white edifice surrounded by a forest of green trees, with the Austrian Alps providing a backdrop. The castle, which is 40 kilometres (25 miles) south of Salzburg in Werfen, was constructed in the eleventh century to ward off invaders and safeguard the Archbishopric of Salzburg. In addition, the castle has been used as a home, a hunting lodge, a jail, and a police academy. It appears to be recognisable because it appears in the children's song "Do Re Mi" from The Sound of Music.
    
8. Burg Heidenreichstein: Heidenreichstein, regarded as the best moated castle in Austria, was constructed on a hilltop during the end of the 12th and the beginning of the 13th centuries, and it underwent renovations in the 15th and 16th centuries. Long owned by the Palffy family, it consists of four wings with three circular corner towers. Count Kinsky currently resides there full-time.
    
9. Burg Petersberg: Above the oldest town in Carinthia, Friesach, sits the ruined fortress known as Burg Petersberg. The Petersberg Castle was constructed around 1076 by Archbishop Gebhard of Salzburg to keep Emperor Henry IV from escaping over the Alps. When King Conrad III of Germany returned from the Second Crusade in 1149, and when Richard the Lionheart returned from the Third Crusade in 1192, they both lodged in the fortress.
    
10. Landskron Castle: Northeast of Villach, in the Ossiach Tauern mountains, is the site of the abandoned castle known as Landskron. This castle was one of the Habsburg strongholds in Carinthia during the Middle Ages. It passed to the Khevenhüller family in the 16C; their chronicles attest to the opulence of the castle at that time. However, the Khevenhüllers abandoned it during the Thirty Years War. Lightning struck in 1812, starting a fire that damaged most of the interiors and the roof.
