History of Klis Fortress

Klis Fortress has a long history of over two thousand years. It started as a small stronghold built by the ancient Illyrian tribe Dalmatae. Later, it became a royal castle that served as the seat of many Croatian kings. During the Ottoman wars in Europe, it developed into a large fortress that guarded the frontier. However, it was lost and re-conquered several times throughout its history.

Ancient Stronghold of Illyrians and Romans

The first inhabitants of Klis Fortress were the Dalmatae, an ancient Illyrian tribe. They were defeated many times and eventually annexed by the Romans in 9 AD. The Romans called the fortress “Andetrium” or “Anderium,” and later it became known as “Clausura,” which eventually evolved into “Clissa” and then “Klis.” The Romans famously besieged Klis during the Illyrian revolt in Dalmatia.

Arrival of the Croats

Klis was raided by Barbarians after the fall of the Roman Empire. It was ruled by Odoacer and then by Theodoric, who established an Ostrogothic Kingdom. Justinian I captured Dalmatia in 537, making Klis part of the Byzantine Empire. The fortress was constructed or improved to protect the coastal cities and roads from Slav attacks.

In 614, Avars and Slavs destroyed Salona, forcing people to flee to Split. Split became important, and in the 7th century, Croats were invited to counter the Avar threat to the Byzantine Empire and drove them out.

Royal Castle

Klis was an important stronghold for Croatian rulers from the 7th century onwards. In the 9th century, it became the seat of power for Duke Mislav. After his death, Klis was ruled by members of the House of Trpimirović, who developed the stronghold into their capital.

Duke Trpimir I moved the main residence to Klis and built a church and monastery there. He spread Christianity and mentioned Klis as his property and seat of power in a charter.

Knights Templar

The castle of Klis was governed by Croatian nobility under the Hungarian kings from early 12th century. Andrew II of Hungary appointed Pontius de Cruce, Master of the Order, as a regent in Croatia and Dalmatia during the Fifth Crusade. Andrew II granted the estate of Gacka to the Templars for their logistical and financial support given during the campaign.

In 1217, Andrew II gave the castle of Klis to the Templars for its strategic location in the hinterland of Split. However, the Templars lost Klis shortly after, and the king gave them the coastal town of Šibenik in exchange.

Mongol Siege

In March 1242, the Tatars attacked Klis Fortress, believing that Béla IV of Hungary was inside. However, the fortress’s natural defenses proved too strong, and the Tatars failed to capture it. They pursued Béla IV through various Dalmatian towns but were hindered by the Croatian nobility and Dalmatian towns who helped the king escape. As a reward, Béla IV granted these towns and nobles for their aid, except for the city of Split, which did not assist him in his escape.

Šubić ruled over a large portion of modern-day Croatia and Bosnia and appointed his brothers as commissars of Dalmatian cities. Jelena Šubić gave birth to the first Bosnian King, Tvrtko I, who later inherited the Klis Fortress.

Petar Kružić and Uskoks

Klis Fortress was a crucial defensive position during the Ottoman conquest of the Balkans. Petar Kružić, a Croat feudal lord, gathered Croat refugees to resist the Turks. Kružić and his Uskoks functioned independently despite accepting the sovereignty of Habsburg king Ferdinand.

Kružić defended the fortress against the Turkish invasion for more than two and a half decades and fought almost alone against the Ottomans. The Hungarian king’s troops couldn’t come to help, and only the popes were willing to provide some men and money.

Final Ottoman Siege

In 1536, Pope Paul III asserted his rights over Klis fortress in Croatia. Ferdinand I agreed to share the cost of maintaining a garrison there. A relief force of 3,000 infantry commanded by Petar Kružić and others arrived with artillery on March 9, 1537, to prepare for a possible Turkish siege. Suleiman the Magnificent sent 8,000 men to besiege Klis fortress. The Christian relief force was overwhelmed on March 12 and their attempts to help the citadel failed. They surrendered to the Ottomans on March 12, 1537, in exchange for their freedom.

Sanjak Center of Ottoman Bosnia

Klis Fortress was an important administrative center during the Ottoman wars in Europe, serving as the Kilis Sancağı of the Bosnia Eyalet for a century.

In 1596, Split noblemen Ivan Alberti and Nikola Cindro, along with Uskoci, Poljičani, and Kaštelani irregulars, managed to occupy the fortress with the help of dissident elements of the Turkish garrison. Bey Mustafa responded by bringing more than 10,000 soldiers to the fortress. General Ivan Lenković, leading 1,000 Uskoci, came to the relief of the 1,500 Klis defenders. During the battle, Ivan Lenković was wounded and retreated with his men, resulting in the loss of the fortress to the Turks on May 31. Despite the loss, this temporary relief was widely celebrated in Europe and among the local population.

Petar Kružić Fighting the Ottomans

From their well-fortified position in the Klis Fortress, the Turks posed a constant threat to both the Venetians and the local Croatian population in the surrounding area. In 1647, following the Turkish success at Novigrad, it was reported that the Turks had amassed an army of 30,000 troops ready to attack Split. In response, the Signoria dispatched two thousand soldiers along with provisions and munitions to the threatened area. Despite being strong fortresses, both Split and Zadar were clearly in danger.

Klis Fortress ST. VID’S CHURCH

The Klis Mosque / Church

The Klis fortress in Croatia was conquered by the Ottomans who then built a stone mosque with a dome and a minaret on the foundations of an earlier Old Croatian Catholic chapel. The mosque was primarily designed for military and religious use by the garrisons stationed inside the fortress, and it had a simple constructed square with an octagonal stone roof.

Later, the Venetians conquered the fortress from the Ottomans and converted the mosque into a Roman Catholic church after destroying the minaret. The church was dedicated to St. Vitus and has been used as such ever since. It is one of three preserved Ottoman mosques in Croatia, the other two being in the towns of Drniš and Đakovo.

Venetian Domination

In 1420, Ladislaus of Naples sold his “rights” to Dalmatia to the Venetian Republic for 100,000 ducats. However, Klis and Klis Fortress remained under the control of the Kingdom of Croatia.

After several decades of fighting, the Venetians retook Klis during the Candian War (1645-1669) with the support of the local population. From 1669, Klis Fortress was under Venetian control, and they restored and expanded it.

The Venetians advanced up to the present Bosnian/Croatian border after the seventh war with the Turks from 1714 to 1718, taking the whole Sinjsko Polje and Imotski. However, Napoleon dissolved the republic in 1797, and Klis lost its primary strategic significance. As a result, it was captured by the Austrians. The Axis powers occupied Klis Fortress during World War II, marking its last military occupation.

Architecture of Klis Fortress

Klis Fortress is a prime example of defensive architecture in Dalmatia. It is a complex structure comprising three rectangular defense lines that consist of three stone walls that surround a central strongpoint.

Klis Fortress Smithy

Smithy

During the Middle Ages, forging was a crucial craft that was required in every large settlement. Each fortress had a military purpose and for that reason, a specialized blacksmith was needed in these quarters. Forgers were responsible for overseeing the production and repairs of military equipment, shields, and weapons. One of these maintenance facilities was situated inside the Klis Fortress.

Today, this facility has been reconstructed, reviving the nearly forgotten and neglected metal-processing skill.

Klis Fortress Water Tanks

Water Tanks

The Klis fortress heavily relied on its water supply, particularly for the defenders who needed it the most. However, since there were no natural water sources available, seven tanks were constructed to collect rainwater. Out of these, two are located near the protective walls, beneath the third entrance, and were built during the Venetian rule in the 17th century.

Klis Fortress Third Entrance

Third Entry

This one-story stone house has a rich medieval history. It was originally built in a different shape, but due to its age, the Venetians completely demolished it.

It was used as the residence for the weaponry manager.

Initially known as the Prince’s home, it was later named the Turkish Sandzak Beg and Dizdar.

Eventually, during the Venetian period, it became known as the Governor’s residence or simply the Palace. Over time, the Venetians rebuilt it several times during the 17th and 18th centuries, and the Austrians gave it its final form around 1820.

Klis Fortress ST. VID’S CHURCH

St. Vid’s Church

In the past, there was a smaller church located in this area. However, the Osmans destroyed it and built a mosque in its place. Later on, when the Venetians took control of the area, the mosque was transformed into the Church of St. Vid.

During the Venetian rule, probably at the start of the 18th century, a vestibule and an octagonal roof were added to the church. There is also a baroque lavatory with relief decorations, dating back to the 17th century, and a large stone aspersion shaped like a shell.

The Austrians then constructed a new powder magazine in the western part of the position.
