The Temple of Augustus is a well-preserved Roman temple in the city of Pula. Dedicated to the first Roman emperor, Augustus, it was probably built during the emperor's lifetime at some point between 27 BC and his death in AD 14. It was built on a podium with a tetrastyle prostyle porch of Corinthian columns and measures about 8 by 17.3 m, and 14 m high. The richly decorated frieze is similar to that of a somewhat larger and more recent temple, the Maison Carrée in Nîmes, France. These two temples are considered the two best complete Roman monuments outside Italy.

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.
