Trieste Cathedral (Basilica cattedrale di San Giusto Martire), dedicated to Saint Justus, is the seat of the Bishop of Trieste. The first religious edifice on the site was built in the 6th century, using part of the existing structure. Perhaps the entrance to a monument, this was commonly known as the Capitoline Temple, as a pyramidal altar with the symbols of the Capitoline Triad (Jupiter, Juno and Minerva) had been found inside it.
Of the hall there remains part of the mosaic floor, integrated into the present-day floor, which contains markings of the outer walls of the early Christian building. Soon after it was opened for worship, the church was destroyed in the Lombard invasion.
Between the 9th and 11th centuries, two basilicas were erected on the ruins of the old church, the first dedicated to Our Lady of the Assumption and the second, the cathedral, to Saint Justus (San Giusto). The original design of the latter building was subsequently lengthened. In the 14th century the two basilicas were joined by means of the demolition of one nave of either basilica and the construction of a simple asymmetrical façade, dominated by a delicately worked Gothic rose window, as ornate as the new bell tower, using the Romanesque debris stones found on the site and friezes of arms.
The Chapel of Saint Charles Borromeo serves as the burial chapel for the family of the Carlist claimants to the throne of Spain. Among the works of historical interest in the cathedral are the apsidal mosaics depicting Our Lady of the Assumption and Saint Just, laid by master craftsmen from Veneto in the 12th-13th centuries. The small 14th-century church of San Giovanni on the left and San Michele al Carnale on the right, by the entrance to the museum, complete a fine medieval churchyard.
In the square in front of the church is an altar commemorating the consecration and laying down of the arms of the 3rd Army, a column with a halberd and a monument to those who died in the First World War.
Archaeological excavations carried out here in the 1930s laid bare the remains of the Roman forum and civic building constructed on two colonnaded floors with two apses. Two lower-floor columns have been reconstructed.References:
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.
