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:Visby Cathedral (also known as St. Mary’s Church) is the only survived medieval church in Visby. It was originally built for German merchants and inaugurated in 1225. Around the year 1350 the church was enlarged and converted into a basilica. The two-storey magazine was also added then above the nave as a warehouse for merchants.
Following the Reformation, the church was transformed into a parish church for the town of Visby. All other churches were abandoned. Shortly after the Reformation, in 1572, Gotland was made into its own Diocese, and the church designated its cathedral.
There is not much left of the original interior. The font is made of local red marble in the 13th century. The pulpit was made in Lübeck in 1684. There are 400 graves under the church floor.
