Senate Square (Senaatintori) presents Carl Ludvig Engel's architecture as a unique allegory of political, religious, scientific and commercial powers in the centre of Helsinki. It has been the centrum of Helsinki since the city was established in 1640. Russians destroyed Helsinki entirely during the Great Northern War (1713-1721).
When the Finland became an autonomous part of Russia in 1812, the capital was moved from Turku to Helsinki. This started a massive construction programme to enhance the cityscape of Helsinki. The responsibility of the new design was given to German architect Carl Ludvig Engel. He decided that all buildings surrounding the old main square should be reconstructed to solid neoclassical ensemble. Many old buildings were demolished including the church of Ulrika Eleonora.
The Palace of the Council of State was completed on the eastern side of the Senate Square in 1822. The main University building, on the opposite side of the Senate Square, was constructed in 1832. The Helsinki Cathedral on the northern edge of the Senate Square was Engel's lengthiest architectural project. He was working on it from 1818 until his death in 1840. The Helsinki Cathedral — then called the Church of St. Nicholas — dominates the Senate Square, and was finalized twelve years afters Engel's death, in 1852.
A statue of Emperor Alexander II is located in the center of the square. The statue, erected in 1894, was built to commemorate his re-establishment the Diet of Finland in 1863, as well as his initiation of several reforms that increased Finland's autonomy from Russia. The statue comprises Alexander on a pedestal surrounded by figures representing the law, culture and the peasants.
Today, the Senate Square is one of the main tourist attractions of Helsinki. Various art happenings, ranging from concerts to snow buildings to controversial snow board happenings, have been set up on the Senate Square. Several buildings near the Senate Square are managed by the government real estate provider, Senate Properties.
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.
