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 Church of St Donatus name refers to Donatus of Zadar, who began construction on this church in the 9th century and ended it on the northeastern part of the Roman forum. It is the largest Pre-Romanesque building in Croatia.
The beginning of the building of the church was placed to the second half of the 8th century, and it is supposed to have been completed in the 9th century. The Zadar bishop and diplomat Donat (8th and 9th centuries) is credited with the building of the church. He led the representations of the Dalmatian cities to Constantinople and Charles the Great, which is why this church bears slight resemblance to Charlemagne's court chapels, especially the one in Aachen, and also to the Basilica of San Vitale in Ravenna. It belongs to the Pre-Romanesque architectural period.
The circular church, formerly domed, is 27 m high and is characterised by simplicity and technical primitivism.
