Jordan's Castle's early history is somewhat obscure. The earliest authentic reference is to a defence of the castle by Simon Jordan against the O'Neills for three years, until relieved by Lord Deputy Mountjoy in 1601. In 1911 the Belfast antiquarian, Francis Joseph Bigger, bought the castle and restored it, using it to display his extensive collection of antiquities and making it freely accessible to everyone. When he died in 1926, the castle was presented by his executor, Dr Joseph Bigger, to the state on condition that, with its contents, it should be preserved as an Ancient Monument. The contents have since been dispersed among the Ulster Museums general collections and the tower is no longer open to the public.
Jordan's Castle is a rectangular tower house four storeys high. On the north face are two rectangular projections, one containing a stone spiral staircase, the other an inner closet at each level, with those on the lower stages having outlets to the ground. Architecturally there is little evidence to give a definitive date for the castle. The masonry is blue stone rubble with a little freestone in quoins and window jambs. Some of the window details suggest 15th century, but have had so much reconstruction that dating is difficult.
The ground floor chamber is unfloored and the irregular surface of the outcropping rock can be seen. It therefore may have been a storehouse. The main room is apparently on the first floor, which contains its original stone floor supported on a pointed barrel vault. The floors on the second and third storeys are at the original levels but of modern construction, with the beams going at right angles to the original direction. The concrete roof is also an addition. The wall tops retain their stone-flagged rampart walls and archery turrets. The turret to the north-west contains a dovecote, the nest-holes of which are contemporary with the main structure.
The entrance is at the bottom of the north-west tower and leads to a spiral stairway to roof level. It is protected by a machicolation at that level. The projecting towers are connected by a high-level arch which also functions as a machicolation.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.
