The Pantheon of National Revival Heroes is a Bulgarian national monument and an ossuary, located in the city of Ruse. The remains of 39 famous Bulgarians are interred there, including: Lyuben Karavelov, Zahari Stoyanov, Stefan Karadzha, Panayot Hitov, Tonka Obretenova, Nikola Obretenov, Panayot Volov, Angel Kanchev, and others; 453 other participants in Botev's detachment, the Chervena Voda detachment, in the April uprising, and other revolutionaries have been honored by inscription of their names in the interior. An eternal fire burns in the middle under the gold-plated dome.
In order to build the Pantheon in 1977, the 'All Saints' church in the old Rousse cemetery was demolished. The new building was opened to visitors on 28 February 1978. After a public discussion in 2001, the Patheon was 'Christianised' by placing a cross on top of its dome. The St Paisius of Hilendar chapel, as well as a museum exposition, were founded at that time.
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.
