Jaunpils Castle was erected in 1301 by the Master of the German branch of the Livonian Order, Gottfried von Roga. The tower was added in the 15th century. The castle was heavily damaged in war by Swedes in 1625. Later a third floor was added and the old fortress became a manor with all conveniences in the end of the 17th century. The building was partly reconstructed in 18th century. The castle was burned down during the Russian Revolution of 1905. A year later it was rebuilt by architect Wilhelm Bockslaff.
From the 16th century until 1920 the castle belonged to the family of the Baltic German baron von der Recke. One of the family members who lived there in the 18th century was the poet Elisa von der Recke. After the Latvian agrarian reforms of 1920s, the castle complex housed a cattle-breeding experimental station. During the Soviet occupation of Latvia, the interior of the castle was heavily reconstructed and today Jaunpils castle has typical Soviet interiors from the 1960s. More of a manor house than properly a fortified castle, it has now been converted into a hotel.
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.
