La Varde is an 11m long bottle shaped passage grave with 6 capstones and a small oval recess towards the rear. It dates back to Neolithic Age (3000-2500 BC). Originally covered by a mound 18m in diameter and a peristalith. The mound has been partially restored and two capstones are supported by modern pillars. Two layers of paving were recorded above and between which burnt and unburnt human bones, limpet shells and pebbles were found. Fragments of some 150 Neolithic and Early Bronze Age pots were also recovered as well as flint, stone tools, a serpentine ring, Gallo-Roman pottery, querns and fragments of bronze. The chamber had been sealed with a dry stone wall and also included a small slab lined cist set into the floor.
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.
