Nesebar is an ancient city and one of the major seaside resorts on the Bulgarian Black Sea Coast. Due to the city's abundance of historic buildings, UNESCO included Nesebar in to the list of World Heritage Sites in 1983.
Situated on a rocky peninsula on the Black Sea, the more than 3,000-year-old site of Nessebar was originally a Thracian settlement (Menebria). At the beginning of the 6th century BC, the city became a Greek colony. The city’s remains, which date mostly from the Hellenistic period, include the acropolis, a temple of Apollo, an agora and a wall from the Thracian fortifications. Among other monuments, the Stara Mitropolia Basilica and the fortress date from the Middle Ages, when this was one of the most important Byzantine towns on the west coast of the Black Sea. Wooden houses built in the 19th century are typical of the Black Sea architecture of the period.
The Ancient city of Nessebar is a unique example of a synthesis of the centuries-old human activities in the sphere of culture; it is a location where numerous civilizations have left tangible traces in single homogeneous whole, which harmoniously fit in with nature. The different stages of development of its residential vernacular architecture reflect the stages of development of the architectural style on the Balkans and in the entire East Mediterranean region. The urban structure contains elements from the second millennium BC, from Ancient Times and the Medieval period.
The medieval religious architecture, modified by the imposition of the traditional Byzantine forms, illustrates ornamental ceramics art, the characteristic painted decoration for this age. The town has served for over thousands of years as remarkable spiritual hearth of Christian culture.
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.
