The rural church of Kolga-Jaani was evidently built during the last quarter of the 14th century, under the direction of a master craftsman from Tallinn. It was damaged in the Great Northern War and left in ruins for a long period. The 45-meter high steeple was erected in the reconstruction in 1875. The most significant artefact inside the church is a cruficix made probably around the yer 1380.
Between 1890-1917, the man of culture and the great figure of the national awakening period, Villem Reiman (1861-1917), was the pastor of the Kolga-Jaani church and a monument was established in his honour in 1988. On August 16, 1925, a memorial monument was set up to the 17 who had perished during the Liberation War. The statue was destroyed on June 19, 1941 and restored by May 28, 1989.
Ogrodzieniec Castle is a ruined medieval castle originally built in the 14th–15th century by the W³odkowie Sulimczycy family. Established in the early 12th century, during the reign of Boles³aw III Wrymouth, the first stronghold was razed by the Tatars in 1241. In the mid-14th century a new gothic castle was built here to accommodate the Sulimczycy family. Surrounded by three high rocks, the castle was well integrated into the area. The defensive walls were built to close the circuit formed by the rocks, and a narrow opening between two of the rocks served as an entrance.
In 1470 the castle and lands were bought by the wealthy Cracovian townsmen, Ibram and Piotr Salomon. Then, Ogrodzieniec became the property of Jan Feliks Rzeszowski, the rector of Przemy¶l and the canon of Cracow. The owners of the castle about that time were also Jan and Andrzej Rzeszowskis, and later Pilecki and Che³miñski families. In 1523 the castle was bought by Jan Boner.
