Aizupe Manor (Latvian: Aizupes muižas pils) was built in late classicism style in 1823. In 1561 the estate was the property of the Duke, who granted the manor to his counselor Salamon Henning. In 1719, the manor became property of his heirs, and later von Koskulu's, and von Mirbahu's. From 1793 to 1920, the manor was in the hands of the Hahn family.
The manor then remained a 19th century farm complex with residential houses, large barns with ramps, distillery, and a park established between 1830-1840 next to the manor house until the beginning of the 20th century. From 1939 to 1945, it was occupied by the Cīrava Forest School, and from the 1945 to 1985 by the Forest Technical School. Since the 1990s it has been under control of the Cīrava municipal council.
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.
