The buildings of former Daoulas Abbey - a cloister and a 12th century font, an oratory and a monumental 16th century fountain, together with the 18th century conventual house - are an exceptional tribute to Breton art from the 10th century onwards. It was established by Guyomarch IV de Léon in 1173, but there has been at least a church since the 6th century. The former abbey was raided and looted by Vikings.
Daoulas Abbey was secularized in 1771-1792 and moved as a private property. The abbey has been renowned since 1986 for the quality and originality of its archaeological, historical or ethnological exhibitions organised in collaboration with some of the most known world wide museums. The abbey houses a superb medicinal garden with over 250 species. It is still structured and organised like most middle age/renaissance convent or monastery gardens.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.
