The Holy Forty Martyrs Church is a medieval Eastern Orthodox church constructed in 1230 in the town of Veliko Tarnovo in Bulgaria, the former capital of the Second Bulgarian Empire. It was built and painted on the order of Bulgarian tsar Ivan Asen II in honour of his important victory near Klokotnitsa over the Despotate of Epirus in 1230. The name of the church came naturally as the battle took place on the day of the feast of Holy Forty Martyrs of Sebaste. A royal church during the reign of Ivan Asen II, it was the main church of the Great Lavra monastery at the foot of Tsarevets on the left bank of the Yantra River.
In the first years of Ottoman rule, the church preserved its Christian character, possibly until the first half of the 18th century. It was then converted to a mosque, with the mural paintings, the icons and the iconostasis being destroyed and alterations being made to the structure itself in 1853. Only a limited number of paintings are preserved, primarily from the northern half of the narthex's west side.
The Holy Forty Martyrs Church, an elongated six-columned basilica, has three semicircular apses and a narrow narthex from the west. Another building was added later to the west side of the church. The church interior was covered with mural painting probably in 1230. On the western addition some of the outer decoration survived revealing the traditional arches and coloured small ceramic plates inserted into the wall. It is not clear if the church has frescoes painted on the outer walls.
The church contains some of the Bulgarian Empire's most significant historical records, including Omurtag's Column, Asen's Column and the Border Column from Rodosto from the rule of Khan Krum. The columns of Khan Omurtag and Khan Krum are written in the Greek language. The inscription of the column of Krum 'Fortress of Rodostro' has been turned upside down. The inscription of Omurtag is about the building of a new glorious palace on the Danube river, but its location is unknown. The second part of the inscription is a legacy for following generations to remember the deeds of Omurtag. These columns were placed in the church by Ivan Asen II as a tribute to his mighty ancestors.
References:The Clementinum is a historic complex of buildings in Prague. Until recently the complex hosted the National, University and Technical libraries, the City Library also being located nearby on Mariánské Náměstí. The Technical library and the Municipal library have moved to the Prague National Technical Library at Technická 6 since 2009. It is currently in use as the National Library of the Czech Republic.
Its history dates from the existence of a chapel dedicated to Saint Clement in the 11th century. A Dominican monastery was founded in the medieval period, which was transformed in 1556 to a Jesuit college. In 1622 the Jesuits transferred the library of Charles University to the Klementinum, and the college was merged with the University in 1654. The Jesuits remained until 1773, when the Klementinum was established as an observatory, library, and university by the Empress Maria Theresa of Austria.
