The old church of Haderslev (Gammel Haderslev Kirke) was uilt in the twelfth century as a Romanesque granite church, and the first tower was built in the Gothic time. The present tower is from 1911-12, but many changes have taken place through the centuries.
The altar is made by granite. There is a wooden crucifix, and some brass-candlesticks from 1609. The frescos behind the altar have a motive from the Apocalypse. The baptismal font is from the thirteen century, and a very fine example of Danish Romanesque granite style.
The pulpit has parts from a Renaissance pulpit from 1609, but has been changed in 1871. The balcony is from 1706, when it was necessary to have more seats in the church. The brass chandeliers are from different ages. In the middle there is a Baroque chandelier from the seventeenth century. On the eastern side a Renaissance chandelier from the sixteenth century and a copy on the western side.
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.
