Poznań Fara is one of the city's most recognizable landmarks, the most important Christian temple alongside the Cathedral and the finest example of Baroque architecture in Poland.
Built between 1651 and 1701, the structure was engineered by Polish and Italian masters in the Baroque style, who also incorporated Roman architectural aspects such as the monumental corinthian columns in the interior. In the mid-18th century Pompeo Ferrari designed the main altar standing at 17 meters in height and the main entrance from the Old Town. In 1876 an organ constructed by Friedrich Ladegast was installed inside the Church. The Fara, like most of the city, was spared from destruction during World War II and is currently part of the Roman Catholic Archdiocese of Poznań.

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.
