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 ancient Argos Theater was built in 320 BC. and is located in Argos, Greece against Larissa Hill. Nearby from this site is Agora, Roman Odeon, and the Baths of Argos. The theater is one of the largest architectural developments in Greece and was renovated in ca 120 AD.
The Hellenistic theater at Argos is cut into the hillside of the Larisa, with 90 steps up a steep incline, forming a narrow rectilinear cavea. Among the largest theaters in Greece, it held about 20,000 spectators and is divided by two landings into three horizontal sections. Staircases further divide the cavea into four cunei, corresponding to the tribes of Argos A high wall was erected to prevent unauthorized access into the theatron and may have helped the acoustics, but it is said the sound quality is still very good today.
Around 120 CE, both theaters were renovated in the Roman style.
