Pfünz Roman Fort, Castra Vetoniana, was a Roman cohort camp near Pfünz, a village in the municipality of Walting. It was built in about 90 AD on a 42-metre-high Jurassic hillspur between the valley of the Altmühl and that of the Pfünzer Bach stream. it is a component of the Rhaetian Limes which was elevated in 2005 to the status of a UNESCO World Heritage Site.
Of historical importance are the remains of the double V-shaped ditches hewn out of the rock in front of the position, the one on the western rampart being the best preserved. In 1998, as part of the construction of a high pressure water system, the Bavarian State Office for Monument Protection carried out further test excavations. The archaeological record and rich finds from Pfünz, some of which are very rare, are seen as reasons for further studies in the future.
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.
