Monteserico Castle is situated on a hill in a strategic position for controlling commercial traffic on the Appian Way that passed nearby. First documented in 1041, the year of a famous battle between the Byzantines and the Normans, it became a domus during the Swabian period and a royal farmstead under the Angevins. The Monteserico Castle communicated with the Garagnone Castle and the Gravina Castle (commissioned by Frederick II) through signal torches to alert of approaching enemies.
Destroyed in the early 1500s, it underwent restoration in several phases from the 18th to the 19th century and has recently been the subject of restoration efforts.
In 1989, the municipality of Genzano di Lucania acquired ownership of the building.
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.
