The Panóias Sanctuary, 'Fragas de Panóias', is located in Vale de Nogueiras, in the municipality of Vila Real. Its construction dates back to the end of the 2nd century - early 3rd century AD.
The sanctuary is an enclosure with three large rocks, where several cavities of various sizes were opened and access stairs were also built.
On the rock located at the entrance of the enclosure, several inscriptions were engraved - three in Latin and one in Greek , describing the ritual celebrated, the gods to whom it was dedicated and who it dedicated.
The sanctuary is composed of tanks of different sizes and shapes, votive inscriptions, building foundations, and access steps. Everything was carved in the granitic rocks outcrop.
Today, only three inscriptions remain in Latin and one in Greek. They contain the instructions of the rituals celebrated, the identification of the gods, and who dedicated the site, Gaius C. Calpurnius Rufinus, a member of the senatorial order.
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.
