The Serbian Orthodox Cetinje Monastery was founded between 1701 and 1704 by Prince-Bishop Danilo I on the site of the former court of Ivan Crnojević (founded 1485).
Cetinje was attacked by Ottomans on 25 September 1692. Instead of fighting, Venetians entered negotiations, and reached an agreement to abandon the monastery under honorable terms. However, they mined a monastery with a time bomb, which set of in the evening hours, right after Venetians retreated and as the Ottomans were victoriosly entering the monastery, killing many of them in the process.
Vladika Danilo re-established the monastery in 1701 or 1704 and added a tablet with the coat of arms of the Crnojević family, and a dedication to Ivan Crnojević. Before 1714, it was burnt, and then it was reconstructed yet again around 1743 by Metropolitan Sava Petrović Njegoš. Cetinje became again the center of spiritual, cultural and political life of the Prince-Bishopric of Montenegro.
The last time monastery was devastated was in 1785, when Mahmud Pasha Bushati sacked Cetinje. Ultimately defeated at Battle of Krusi, his decapitated head is since then kept as a relic in the monastery. It has been built on several times, the current appearance dates to 1927. The original site of the monastery, known as Ćipur was used in 1886 by Prince Nicholas of Montenegro for his Court church. The position of the newly built church follows the lineup of the original one from inside the monastery complex. Today its ruin along with couple of pillars can be seen.
There are several relics in the monastery: remains of St. Peter of Cetinje, right hand of John the Baptist, particles of the True Cross, icon of the Philermos Mother of God, royal crown of Serbian king Stephen Uroš III Dečanski, among others.
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.
