The Roman mausoleum of Córdoba is an ancient structure in the Jardines de la Victoria, Córdoba. It is a funerary monument of cylinder-shaped that corresponded to a group of funerary monuments of the Republican era, built in the 1st century AD. It was discovered in 1993 during archaeological excavations.
It includes the chamber tomb that housed the Urn, as well as remains of the basement, cornices, and crenellated parapet. Unusual for such structures in Roman Iberia, it may have been designed by an Italian architect, due to similarities to other mausoleums in Rome and the rest of Italy. Its size also suggests that it belonged to a wealthy family.
The mausoleum is located near the road that connected the ancient city with Hispalis (now Seville), and exited from the city by the western gate, or 'Porta Principalis Sinistra' (Puerta de Gallegos). The archaeological site also includes remains of the pavement of the latter.
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.
