The San Giovanni in Fiore Abbey date back to Joachim da Fiore's trip to La Sila in Calabria in 1188. Archaeological excavations have shown the presence of Joachim's first edifice, which was finished in 1198, in the Iure Vetere locality. The construction of the abbey was approved by Queen Constance of Hauteville after a Joachim's visit in her court at Palermo.
After Joachim's death in 1202, the first monastery and its annexed edifices were burned by a fire in 1214. The monks decided to abandon the location of Iure Vetere, also due to its difficult climatic situation.
In 1215 a site not far from the previous one was chosen, near the Neto river valley. The new abbey was completed in 1230, in the Romanesque style. In later centuries features were remodeled in different styles, including a Baroque style church interior.
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.
