About 1300, a knight named Conrad von Tronecken is mentioned in document for the first time, and then somewhat later the Feste Troneck (fortification), which, however, is probably much older. Having been destroyed several times, by Cologne, Imperial and French troops, and then finally by an earthquake, only remnants of Dhronecken castle are left now, although a corner tower can still be climbed.
On the old castle's foundations in modern times, commercial buildings were built, and also a bigger, tall building – called the Schloss – which is today used as a forester's office. Also, a barn with beam construction serves as a community centre for the municipality of Dhronecken. The attractively laid-out castle gardens have been continuously planted and tended since 1985.
Below the castle is found a nature play area on both sides of a brook. A ford with stepping stones, a forumlike playing and gathering place on a slope, made out of mighty stone blocks, wooden footbridges over wetlands left in their natural state, playing houses, a suspension bridge and a monorail are the great attractions not only for children, but also for adults.
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.
