On Ristimäki hill in Ravattula, remains of an early medieval church were found in 2013. The remains have been dated to the late 12th century–early 13th century, in other words to the end of the Finnish Crusade period and the Early Middle Ages. The church is so far the oldest in Finland and also the only one dating from the period before the establishment of Finnish parish system. Ristimäki is exceptionally well preserved: the site comprises a church, a churchyard that served as burial ground, and a fence surrounding the churchyard.
Ristimäki (lit. Cross Hill) church was a wooden building that was constructed on a stone footing. The church consisted of two rooms: in the western end, there was a square nave and in the eastern end, a slightly smaller narrow choir in which the altar was located. The walls were presumably built by using a horizontal timbering technique and the floor was covered with planks. Today, only the stone footing and the foundation of the altar remain of the Ristimäki church. The corners of the church building and the location of the altar have been marked on the ground.
The church remains are surrounded by a churchyard with dozens of graves. Thus far only a few graves have been archaeologically examined. Most graves are located right in the vicinity of the church as it was regarded as the most valuable place for burying. According to radiocarbon datings, the burial ground may have already been in use a century before the construction of the church begun. Remains of a stone setting of a fence that surrounded the churchyard have so far been found on the south-western side of the hill.
On the basis of natural scientific datings and finds, it seems that the use of the church and the churchyard ceased during the second quarter of the 13th century. Perhaps the church was destroyed by fire, or it was abandoned and left to decay. Around that time, the parochial organisation in Finland began and the religious life appears to have concentrated in the newly established parish centre.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.
