The oldest part of Klinte Church is the base of the tower, which is from the first half of the 13th century and built in a decidedly Romanesque style. It is the only remaining part of an earlier, Romanesque church. Around the year 1300, the choir and nave of this church was replaced by the presently visible, Gothic choir and nave. During this time the upper part of the tower was also added.
Externally, the base of the tower has a Romanesque portal and windows. The upper part of the tower displays Gothic windows. The choir portal is furthermore noteworthy due to its capitals, an accomplished example of stone sculpture from the time.
Internally, the choir vault is decorated with frescos similar to those in Rone Church. In the eastern window of the choir, a few original stained glass window panes survive, depicting religious scenes. They have been assumed to have been made by the same artisan who made the stained glass windows of Alskog Church. Among the church furnishings, the triumphal cross is medieval, dating from the 15th century. The sandstone altarpiece bears the date 1643, and was carved by the sculptor Gert van Eghen. The baptismal font is from 1667, and the pews also largely date from the 17th century.
References:Celje Castle was once the largest fortification on Slovenian territory. The first fortified building on the site (a Romanesque palace) was built in the first half of the 13th century by the Counts of Heunburg from Carinthia on the stony outcrop on the western side of the ridge where the castle stands. It had five sides, or four plus the southern side, which was a natural defence. The first written records of the castle date back to between 1125 and 1137; it was probably built by Count Gunter. In the western section of the castle, there was a building with several floors. Remains of the walls of this palatium have survived. In the eastern section, there was an enclosed courtyard with large water reservoirs. The eastern wall, which protects the castle from its most exposed side, was around three metres thicker than the rest of the curtain wall. The wall was topped with a parapet and protected walkway.
