According to some historical sources, Dragonara Castle was built in the first half of the 13th century. In the second half of the 14th century, the castle, to ensure the safety of the fishing village of Camogli, was repeatedly reinforced, receiving the necessary weapons from the Republic of Genoa.
In the 14th century, the Dragonara Castle was attacked several times. Well documented are the assaults made by Gian Galeazzo Visconti, Lord of Milan, and the one made by Nicolò Fieschi in 1366.
Between 1428 and 1430, the castle was considerably enlarged and reinforced, especially the adjacent watchtower. In 1438, the Duchy of Milan besieged the castle, destroying its walls. A few years later, the inhabitants of the seaside village built new walls around the castle.
In 1448, due to a conflict between Camogli, Recco and Genoa, the Republic demanded the immediate destruction of the castle. The castle was destroyed, but it was rebuilt again only six years later and given to the Doge of Genoa.
In the 16th century, the castle was abandoned as a defensive post, and it was used as a prison.
In the seventies of the 20th century, after decades of neglect, the building was recovered and converted into an aquarium, hosting specimens of the marine fauna typical of these waters. At the closing of the aquarium, the fish were transferred to the Genoa aquarium.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.
