Demir Baba Teke is a 16th-century Alevi mausoleum (türbe) near the village of Sveshtari. It is thought to be the resting place of Demir Baba, a 16th-century Alevi saint. The tomb itself is a heptagonal building constructed out of local sandstone. It has a lower rectangular antechamber and is covered by a hemispherical dome 11 metres (36 ft) in height. Demir Baba's grave lies in the middle of the heptagonal inner premises. Constructed out of bricks and wood, the sarcophagus is 3.74 metres in length and is positioned with the saint's head pointing southwest. The sarcophagus is usually entirely covered by gifts and is only rarely displayed to Alevi pilgrims.
The mausoleum is thought to have been constructed in the 16th century on what was probably an ancient Thracian holy site from the 4th century BC. A cult complex (tekke) gradually emerged around the türbe. This included a holy spring, a mosque that was mentioned by travellers in the 18th and 19th centuries but was then destroyed, and a wooden public kitchen (imaret) which was pulled down in 1976 due to its deteriorating condition. The tekke features that have survived until today are the mausoleum, the holy spring, a residential building and a low stone fence surrounding the complex. A small exhibition in the residential building explains the story of the Alevis and Demir Baba himself.
Demir Baba Teke was proclaimed a monument of culture of local importance in 1970 by the government of the then-People's Republic of Bulgaria. The mausoleum was renovated in 1991–1994: the decaying wooden floor was replaced with a new one and the building's interior decorative elements (including the 19th-century murals) were reconstructed.
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.
