Vaduz Cathedral, or Cathedral of St. Florin was built in 1874 by Friedrich von Schmidt on the site of earlier medieval foundations. Its patron saint is Florinus of Remüs (Florin), a 9th-century saint of the Vinschgau Valley. Prince Franz Joseph II of Liechtenstein and his wife Countess Georgina von Wilczek were both buried in the cathedral in 1989. Elisabeth von Gutmann was buried there too.
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.
