Medieval Hum town was first mentioned in 1102 in the deed of gift by Marquis Ulrich II. The passage through the early 12th century double entrance gates, and then this one from 1562 leads us into the square. The exceptionally small area has all town features: the town loggia, nobility and folk houses, and the parish church with the priest residence.
The castle was located on the site of the current Church of the Assumption of the Blessed Virgin Mary (erected in 1802) on the highest point of the town, which allowed its control of the surrounding area. Rectangular in shape, 30 x 35 meters (typical dimensions of the time) and connected by two streets with the twin town gates, which facilitated better communication and protection. The castle was entered from the inside, from the town. Despite its basic defensive purpose, in the earlier era it was a seat of its owners – the feudal lords under the Patriarch of Aquileia.
Ever since the prehistoric times until the ruins of the Venetians in 1797, Hum was a defensive border town, full of life, conflicts, different rulers, war and peace. From the antiquity to the Late Middle Ages, it was used as a defensive castle of an estate. Often destroyed and renovated, it finally fell under the Venetian rule in 1412, which restored it completely to defend its own borders. Its most probable final fall occurred during the Uskok War (1612-1618), when the entire town was burned down and the castle was never renovated. Its stone was gradually being taken for building houses. Any trace of it was finally lost following the erection of the church.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.
