The Kommern Open Air Museum (LVR-Freilichtmuseum Kommern) is one of the largest open air museums in Europe, covering an area of over 95 hectares and displaying around 67 historic buildings from the Prussian Rhine Province.
Around 67 buildings, including farmyards, wind mills, workshops, village community buildings like schools, bakehouses, dancing halls and chapels, all of which originated on the territory of the former Prussian Rhine Province and its predecessors, have been gathered together in four groups. Arable fields, vegetable gardens and orchards complete the picture. The exhibits come predominantly from the Westerwald/Middle Rhine region, from the Eifel mountains and Voreifel foothills, from the Lower Rhine and from the Bergisches Land. They portray everyday life from the 15th century. Under construction is another group of buildings, the Rhineland Marketplace, which illustrate the rural and small-town life of the Rhineland, both at home and work, from the 1950s to the 1980s. With that the Kommern Open Air Museum will also become a museum of everyday culture of life in the 20th century.
In addition the museum has permanent and changing exhibitions in its role as the Rhenish State Museum for Folk Culture. The Kommern Open Air Museum has an annual programme with around 70 special events.
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.
