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.
The Walls of Constantinople are a series of defensive stone walls that have surrounded and protected the city of Constantinople (today Istanbul) since its founding as the new capital of the Roman Empire by Constantine the Great. With numerous additions and modifications during their history, they were the last great fortification system of antiquity, and one of the most complex and elaborate systems ever built. They were also the largest and strongest fortification in both the ancient and medieval world.
Initially built by Constantine the Great, the walls surrounded the new city on all sides, protecting it against attack from both sea and land. As the city grew, the famous double line of the Theodosian Walls was built in the 5th century. Although the other sections of the walls were less elaborate, they were, when well-manned, almost impregnable for any medieval besieger.
