Zehra is one of the earliest Slovak settlements in the region. In the later feudal period it formed part of the castle domain, with a manor in the village. The village was first mentioned in local records in 1245, when Count Johann of Žehra was given permission to construct a church there by the church authorities of Spiš.
The Church of the Holy Spirit was completed in 1275. It is noted both for its picturesque appearance, perched on a mound above the village, and for its remarkable series of wall paintings. These have survived despite much damage to the building, including a fire in the 15th century which burnt down its original ceiling. The remaining building is a single nave structure, topped with onion-shaped domes of the 17th century.
The oldest wall paintings are a set of eight consecration crosses, marking the spots where the original building was christened with holy chrism, and thus dating back to the 13th century. Later in the 13th century, a second stage of painting is marked by the depiction of Golgotha on the tympanum of the church's south doorway. Frescoes in the sanctuary, dating from the 14th century, showing Byzantine influence, include representations of the Last Judgement, the Last Supper, the Deposition and Saints Cosmas and Damian, the patron saints of doctors. On the north wall are two notable 'framed' frescoes, one depicting the Pietà, the other showing a symbolic Tree of Life which dramatises the triumph of the Church over the Synagogue.
These paintings were preserved because after an outbreak of plague in the 17th century, the interior of the church was covered with lime plaster for disinfection. They were discovered again in the 1950s when the lime was removed using cottage cheese - effective for this purpose because it contains casein.
The church was declared a Czechoslovak National Monument in 1985, and in 1993 was listed as a World Heritage Site together with the nearby Spiš Castle, Spišská Kapitula and (since 2009) the nearby town of Levoča.
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.
