From its origin as a small stronghold built by the ancient Illyrian tribe Dalmatae, becoming a royal castle that was the seat of many Croatian kings, to its final development as a large fortress during the Ottoman wars in Europe, Klis Fortress has guarded the frontier, being lost and re-conquered several times. Due to its location on a pass that separates the mountains Mosor and Kozjak, the fortress served as a major source of defense in Dalmatia, especially against the Ottoman advance, and has been a key crossroad between the Mediterranean belt and the Balkan rear.
Since Duke Mislav of the Duchy of Croatia made Klis Fortress the seat of his throne in the middle of the 9th century, the fortress served as the seat of many Croatia's rulers. The reign of his successor, Duke Trpimir I, the founder of the Croatian royal House of Trpimirović, is significant for spreading Christianity in the Duchy of Croatia. He largely expanded the Klis Fortress, and in Rižinice, in the valley under the fortress, he built a church and the first Benedictine monastery in Croatia. During the reign of the first Croatian king, Tomislav, Klis and Biograd na Moru were his chief residences.
In March 1242 at Klis Fortress, Tatars who were a constituent segment of the Mongol army under the leadership of Kadan suffered a major defeat while in pursuit of the Hungarian army led by King Béla IV. After their defeat by Croatian forces, the Mongols retreated, and Béla IV rewarded many Croatian towns and nobles with 'substantial riches'. During the Late Middle Ages, the fortress was governed by Croatian nobility, amongst whom Paul I Šubić of Bribir was the most significant. During his reign, the House of Šubić controlled most of modern-day Croatia and Bosnia. Excluding the brief possession by the forces of Bosnian King, Tvrtko I, the fortress remained in Hungaro-Croatian hands for the next several hundred years, until the 16th century.
Klis Fortress is probably best known for its defense against the Ottoman invasion of Europe in the early 16th century. Croatian captain Petar Kružić led the defense of the fortress against a Turkish invasion and siege that lasted for more than two and a half decades. During this defense, as Kružić and his soldiers fought without allies against the Turks, the military faction of Uskoks was formed, which later became famous as an elite Croatian militant sect. Ultimately, the defenders were defeated and the fortress was occupied by the Ottomans in 1537. After more than a century under Ottoman rule, in 1669, Klis Fortress was besieged and seized by the Republic of Venice, thus moving the border between Christian and Muslim Europe further east and helping to contribute to the decline of the Ottoman Empire. The Venetians restored and enlarged the fortress, but it was taken by the Austrians after Napoleon extinguished the republic itself in 1797. Today, Klis Fortress contains a museum where visitors to this historic military structure can see an array of arms, armor, and traditional uniforms.References:
Soave castle was built in 934 to protect the area against the Hungarian invasions. It was remodelled by Cansignorio of the Scaliger family in the mid-1300s. in 1365 Cansignorio had the town walls erected and the Town hall was built in the same year.
The castle underwent various vicissitudes until, having lost its strategic importance, it was sold on the private market in 1596. In 1830 it was inherited by Giulio Camuzzoni who restored the manor and in particular the surroundings walls (with is twenty-four towers), the battlements and living-quarters.
Soave castle is a typical medieval military edifice, commanding the neighbourhood of the city from the Tenda Hill. It comprises a mastio (donjon) and three lines of walls forming three courts of different size. The outer line, with a gate and a draw bridge, is the most recent, built by the Venetians in the 15th century. It houses the remains of a small church from the 10th century.
The second and larger court, the first of the original castle, is called della Madonna for a fresco portraying St. Mary (1321). Another fresco is visible after the door leading to the inner court, and portrays a Scaliger soldier. The mastio is the most impressive feature of the castle. Bones found within showed it was used also as prison and place of torture.
The House called del Capitano (the Scaliger commander) houses Roman coins, weapons parts, medals and other ancient remains found during the most recent restoration. Adjacent is a bedroom with a 13th-century fresco with St. Mary and Madeleine and a dining room with medieval kitchenware. Another room houses the portraits of the most famous Scaliger figures: Mastino I, Cangrande, Cansignorio and Taddea da Carrara, wife of Mastino II; the portrait of Dante Alighieri testify an alleged sojourn of the poet in the castle.
