The Mělník castle belongs to the most important sights of this town. Since Princess Ludmila, the grandmother of the Good King Wenceslas, who was born in Mělník, the castle has been the residence of the queen widows of Bohemia. Under Emperor Charles IV, Mělník became a royal town. His last wife built the chapel of the castle with its gothic vaults.
The last queen who resided in Mělník, was the wife of king Jiri of Podebrady during the 15th century. In the following years, the estate of Mělník became the property of different noble families. In 1542 the castle was reconstructed in renaissance style and the two arcades, richly decorated with sgrafitto patterning, have been added.
During the Thirty Years War, 1618-1648, the castle was abandoned. In the year 1646 Count Czernin started a major reconstruction and had the early barrock southern wing added. The Count purchased the Mělník Estate from the Emperor Ferdinand II. The heiress of the Czernin family, Countess Ludmila Czernin, married Prince August Anton Lobkowicz in 1753. With the exception of the Second World War and the 41 years of communist rule, Mělník Castle remained in the Lobkowicz family.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.
