Šamorín Gothic church is composed of three naves. The eastern part of the church, an early Gothic holy cave, was constructed in the first half of the thirteenth century. Its outer walls bear traces of the late reconstruction. This, and the supporting pillars, may have been the work of Bratislava's mayor Alexander’s son Karol shortly after 1287. The holy cave was lit by five arched windows. Among these, only three east side windows are original, made in the first half of the 13th century. The two remaining windows on the south side were refurbished in the Gothic style in the 15th century, then in the Baroque style in the 18th century and, finally, enlarged in 1931.
After reconstruction around 1290, the whole church was decorated with painted figures, which were later covered but were revealed again during restoration. There are also paintings of standing Saints, a depiction of Holy Mary's death and Judging Jesus. The north side wing was built/rebuilt later, probably after some kind of a disaster, fire or possibly flood.
The organ case dates from the second half of the 19th century. The wooden gate on the outside of the north hall was made in 1844; the altar was made of red marble in 1904.
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.
