Frijsenborg is one of Denmark's most remarkable estastes. The impressive main building was designed between 1859 and 1867 by one of Denmark's leading architects, Ferdinand Meldahl, for Count C. E. Krag-Juel-Vind-Frijs. The Frijsenborg manor, the result of the conversion of a more modest Baroque-period house, was built in a period when Danish estates enjoyed great wealth and influence. Their prosperity caused a boom in the building of manors on a scale unseen since the heyday of the nobility in the Renaissance. Architects of the era found inspiration for conversions and new buildings from the architecture of the Renaissance. Frijsenborg manor epitomises this Renaissance Revival. Today Frijsenborg is an office of farming and forestry company.

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.
