National Museum of Montenegro in Cetinje is a complex institution consisting of four museums: Museum of History, the Art Museum with the Modern art gallery Dado Duric, the Ethnographic Museum and the newly founded Archaeological Museum with Lapidarium.
Collection of museum exhibits on the territory of present-day Montenegro can be traced back to the ancient past. In a modern sense, however, it is possible to record the traces as of late 15th century, the time when Cetinje was established as a political and spiritual centre of Montenegro. The residences of Ivan Crnojevic and the Vranjine Metropolitan, built at the time, contained rich stores of cultural-historical treasure as well as archive and book collections. During the sixteenth and seventeenth century, collecting is to be associated chiefly with the Montenegrin Metropolitans, while the nature of the collected items relates primarily to church history.
The museum possesses the Oktoih Prvoglasnik, a significant printed work from the late 15th century. It also host the original icon of Our Lady of Philermos, which had been in the possession of the Order of St. John since the Crusades. The icon was removed from the St. John's Co-Cathedral in Valletta by Grand Master Ferdinand von Hompesch zu Bolheim when the Order was expelled from Malta by the French in 1798.
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.
