The Museum of Mosaics in Devnya, Bulgaria, is situated on the remains of a Late Roman villa known as the House of Antiope. Founded in 1976 through archaeological research, the villa dates back to the late 3rd or early 4th century AD. The museum showcases mosaics from the Roman and early Byzantine city of Marcianopolis, along with other archaeological artifacts.
The villa, almost square in shape, features 21 rooms around an inner courtyard, with a total area of 1,409 m2. The museum building, designed by architect Kamen Goranov, covers the western part of the villa. However, there have been concerns about the building's structural integrity, with visible cracks and sinking due to groundwater.
Three of the mosaics are exhibited in situ and the remaining have been moved from their original locations in order to be conserved and restored. As a whole, the mosaics were laid out using the opus tessellatum (tiles aligned in horizontal or vertical lines) and opus vermiculatum (tiles aligned so as to draw an outline around the shapes) techniques. The tiles were made of marble, clay, limestone and coloured glass and include 16 colour varieties.
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.
