Graz old town is one of the best-preserved city centres in Central Europe. The oldest settlement on the ground of the modern city of Graz dates back to the Chalcolithic Age. However, no historical continuity exists of a settlement before the Middle Ages. During the 12th century, dukes under Babenberg rule made the town into an important commercial center. Later, Graz came under the rule of the Habsburgs, and in 1281, gained special privileges from King Rudolph I.
In the 14th century, Graz became the city of residence of the Inner Austrian line of the Habsburgs. The royalty lived in the Schloßberg castle and from there ruled Styria, Carinthia, most of today's Slovenia, and parts of Italy.
In the 16th century, the city's design and planning were primarily controlled by Italian Renaissance architects and artists. One of the most famous buildings built in this style is the Landhaus, designed by Domenico dell'Allio, and used by the local rulers as a governmental headquarters.
Graz bear witness to an exemplary model of the living heritage of a central European urban complex influenced by the secular presence of the Habsburgs and the cultural and artistic role played by the main aristocratic families. They are a harmonious blend of the architectural styles and artistic movements that have succeeded each other from the Middle Ages until the 18th century, in the many neighbouring regions of Central and Mediterranean Europe. They embody a diversified and highly comprehensive ensemble of architectural, decorative and landscape examples of these interchanges of influence.
In 1999, Graz was added to the UNESCO list of World Cultural Heritage Sites, and the site was extended in 2010 by Schloss Eggenberg.References:
The Kalozha church of Saints Boris and Gleb is the oldest extant structure in Hrodna. It is the only surviving monument of ancient Black Ruthenian architecture, distinguished from other Orthodox churches by prolific use of polychrome faceted stones of blue, green or red tint which could be arranged to form crosses or other figures on the wall.
The church is a cross-domed building supported by six circular pillars. The outside is articulated with projecting pilasters, which have rounded corners, as does the building itself. The ante-nave contains the choir loft, accessed by a narrow gradatory in the western wall. Two other stairs were discovered in the walls of the side apses; their purpose is not clear. The floor is lined with ceramic tiles forming decorative patterns. The interior was lined with innumerable built-in pitchers, which usually serve in Eastern Orthodox churches as resonators but in this case were scored to produce decorative effects. For this reason, the central nave has never been painted.
The church was built before 1183 and survived intact, depicted in the 1840s by Michał Kulesza, until 1853, when the south wall collapsed, due to its perilous location on the high bank of the Neman. During restoration works, some fragments of 12th-century frescoes were discovered in the apses. Remains of four other churches in the same style, decorated with pitchers and coloured stones instead of frescoes, were discovered in Hrodna and Vaŭkavysk. They all date back to the turn of the 13th century, as do remains of the first stone palace in the Old Hrodna Castle.
In 2004, the church was included in the Tentative List of UNESCO"s World Heritage Sites.
