Ad Quintum was an ancient Roman city in Illyricum, on the Via Egnatia connecting Dyrrhachium with Byzantium. The settlement was probably founded in the late 2nd or in the early 3rd century AD, and continued to be populated until the 4th century AD. Its well preserved ruins can be seen near the present-day village Bradashesh, right next to the SH7 road. The site was extensively excavated around 1968 which uncovered a fine Roman villa and a remarkably well-preserved thermae (bathhouse) taking advantage of the abundant springs nearby.
The bathhouse consists of five main rooms. At the eastern end there is an apsed exedra that was used as a dining room. This connects to the small rectangular cold plunge-bath.
The apodyterium (undressing room) also survived with fine paintings and frescoes on its walls. Further to the western end of the building the ruins of the laconicum (heated sweating room) can be seen with the traces of the hypocaust (underfloor heating), along with the adjacent praefernium (furnace).
References: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.
