De Trompenburgh is a 17th-century manor house designed by Daniel Stalpaert and built for Admiral Maarten Tromp, one of the naval heroes of the Dutch Republic. The house is almost entirely surrounded by water and was built to resemble a ship, even with decks and railings.
Before the current house was built another buitenplaats had been built by Andries Bicker in 1636. The original house dates back to 1654. Through inheritance the house came into the possession of the widow of Van Hellemont Raephorst who remarried on January 25, 1667 with Admiral Cornelis Tromp. The couple redecorated the estate considerably, but the house and their improvements were treasure looted and burned by the French during the rampjaar 1672. It was rebuilt in 1675-1684 by Maarten Tromp's son, Admiral Cornelis Tromp, who called it Syllisburg, after one of his titles. Around 1720 Jacob Roeters came into possession of the estate and he renamed it Trompenburg and had a gilded plaque with an ode by Gerard Brandt in memory of Tromp installed over the entrance in 1725.
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.
