There are three so-called passage graves lying only a couple of hundred meters from the hamlet Mysinge. A passage grave is a grave that is built of enormous stone blocks and surrounded by a cairn. The passage graves in Mysinge lie on the land ridge with openings facing southwest. The grave that has been described here has been excavated several times. It has been established that at least 30-40 persons were buried in the tomb, possibly as many as 70 persons.
Within the tomb there were remains from the greater part of the late Stone Age. It was found that the tomb was used in three different periods, the latest of which being the early Bronze Age. The oldest burial to have taken place is thought to have been in circa 3500 B.C., which makes the tomb the oldest passage grave to have been found in Scandinavia. The other two passage graves have not been excavated, but it would not be surprising if they were from the same period. The passage has 5 stones on each side and opens up to a chamber of 9 stone blocks. The roof of the chamber is made of 3 larger stone blocks with the flat side of the stones always turned inward toward the tomb.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.
