Näsby estate belonged to Uppsala archbishop in 1300s and in 1520s it was donated to Kristina Nilsdotter (Gyllenstierna). In 1571 it was acquired by Gustav Axelsson Baner. Originally built in the 1660s and designed by Nicodemus Tessin the Elder, the current Näsby Castle is located in the picturesque and natural setting of Näsbyviken. The castle was burned to the ground in 1897, but was rebuilt according to the original design on the initiative of Carl Robert Lamm and Dora Lamm who moved into the castle in 1905. Parts of the old castle garden still exist and are well preserved. Today Näsby is a conference center with a hotel and restaurant.
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.
