The castle was probably built in the 13th century most likely in place of an ancient Estonian stronghold. The bailiwick of Karksi was first mentioned in 1248. The stronghold had a chapel dedicated to Apostle Peter. The first reference was made to a local clergyman in 1298. The present stone church, very simple in design, was built in the same place between 1773 and 1778. St. Peter’s Church is in the ruins of Karksi castle. The tower of the church is leaning, the inclination of the tower’s top is 205 cm at the moment. In 1994 it was decided to save the tower using complicated "construction surgery" developed while stabilizing structures in the old town of Tartu. Eight 10- metre-tall bored piles along with concrete beams penetrating foundations form a new bearing surface for the tower. As a result, the further leaning of the tower has stopped.
On the way which takes you to the stronghold, in the former cemetery of the Knights of the Order of the Sword, stands a nice Baroque chapel among trees, built in the early 18th century by Field Marshal George Reinhold von Lieven, the owner of the Karksi manorial estate. The coats of arms of the Lievens and the Mannteuffels have been fixed to the chapel doors. The chapel, similarly, was built with one side on the former foundation and therefore is somewhat leaning. The buildings of the Karksi manor have perished.
The historic city of Trogir is situated on a small island between the Croatian mainland and the island of Čiovo. Since 1997, it has been included in the UNESCO list of World Heritage Sites for its Venetian architecture.
Trogir has 2300 years of continuous urban tradition. Its culture was created under the influence of the ancient Greeks, and then the Romans, and Venetians. Trogir has a high concentration of palaces, churches, and towers, as well as a fortress on a small island. The orthogonal street plan of this island settlement dates back to the Hellenistic period and it was embellished by successive rulers with many fine public and domestic buildings and fortifications. Its beautiful Romanesque churches are complemented by the outstanding Renaissance and Baroque buildings from the Venetian period.
Trogir is the best-preserved Romanesque-Gothic complex not only in the Adriatic, but in all of Central Europe. Trogir's medieval core, surrounded by walls, comprises a preserved castle and tower and a series of dwellings and palaces from the Romanesque, Gothic, Renaissance and Baroque periods. Trogir's grandest building is the church of St. Lawrence, whose main west portal is a masterpiece by Radovan, and the most significant work of the Romanesque-Gothic style in Croatia.
