From the 13th to 16th centuries Kutná Hora competed with Prague economically, culturally and politically. Since 1995 the city center has been a UNESCO World Heritage Site.
Kutná Hora town began in 1142 with the settlement of the first Cistercian monastery in Bohemia, Sedlec Monastery, brought from the Imperial immediate Cistercian Waldsassen Abbey. By 1260 German miners began to mine for silver in the mountain region, which they named Kuttenberg, and which was part of the monastery property. Under Abbot Heidenreich the territory greatly advanced due to the silver mines which gained importance during the economic boom of the 13th century.
In 1300 King Wenceslaus II of Bohemia issued the new royal mining code Ius regale montanorum. This was a legal document that specified all administrative as well as technical terms and conditions necessary for the operation of mines. The city developed with great rapidity, and at the outbreak of the Hussite Wars in 1419 was the second most important city in Bohemia, after Prague, having become the favourite residence of several Bohemian kings. It was here that, on January 18, 1409, Wenceslaus IV signed the famous Decree of Kutná Hora, by which the Czech university nation was given three votes in the elections to the faculty of Prague University as against one for the three other nations.
In 1420 Emperor Sigismund made the city the base for his unsuccessful attack on the Taborites during the Hussite Wars, leading to the Battle of Kutná Hora. The city was taken by Jan Žižka, and after a temporary reconciliation of the warring parties was burned by the imperial troops in 1422, to prevent its falling again into the hands of the Taborites. Žižka nonetheless took the place, and under Bohemian auspices it awoke to a new period of prosperity.
Along with the rest of Bohemia, Kutná Hora passed to the Habsburg Monarchy of Austria in 1526. In 1546 the richest mine was hopelessly flooded; in the insurrection of Bohemia against Ferdinand I the city lost all its privileges; repeated visitations of the plague and the horrors of the Thirty Years' War completed its ruin. Half-hearted attempts after the peace to repair the ruined mines failed; the town became impoverished, and in 1770 was devastated by fire. The mines were abandoned at the end of the 18th century.
The city became part of Czechoslovakia after World War I and the collapse of Austria-Hungary. Kutná Hora was incorporated into the Protectorate of Bohemia and Moravia by Nazi Germany in the period 1939–1945, but was restored to Czechoslovakia after World War II. The city became part of the Czech Republic in 1993 during the dissolution of Czechoslovakia.
Among the most important buildings in the area are the Gothic, five-naved St. Barbara's Church, begun in 1388, and the Italian Court, formerly a royal residence and mint, which was built at the end of the 13th century. The Gothic Stone Haus, which since 1902 has served as a museum, contains one of the richest archives in the country. The Gothic St. James's Church, with its 86-metre tower, is another prominent building. Sedlec is the site of the Gothic Cathedral of Our Lady and the famous Ossuary.
References:Carlsten is a stone fortress built on the orders of King Carl X of Sweden following the Treaty of Roskilde, 1658 to protect the newly acquired province of Bohuslän from hostile attacks. The site of Marstrand was chosen because of its location and its access to an ice free port. Initially a square stone tower was constructed, but by 1680 it was reconstructed and replaced by a round shaped tower. Successive additions to the fortress were carried out, by the inmates sentenced to hard labour, until 1860 when it was reported finished. The fortress was decommissioned as a permanent defense installation in 1882, but remained in military use until the early 1990s.
The fortress was attacked and sieged twice falling into enemy hands. In 1677 it was conquered by Ulrik Frederick Gyldenløve, the Danish military commander in Norway and in 1719 by the Norwegian Vice-Admiral Tordenskjold. At both occasions the fortress was returned to Swedish control through negotiations and treaties.
