The Church of the Blessed Virgin Mary and Archangel Michael in Haczów has original Gothic polychrome decoration from the late 15th century, although the building has been dated to the previous century. At the beginning of the 17th century the church was enclosed by an earthen defensive rampart. Inside a valuable figural wall paintings dating from 1494 can be seen. It is believed that the Haczów church is the biggest Gothic wooden church in Europe.
The church is part of the UNESCO World Heritage Site of Wooden Churches of Southern Lesser Poland and Subcarpathia. The wooden churches of southern Little Poland represent outstanding examples of the different aspects of medieval church-building traditions in Roman Catholic culture.
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.
