Poti Cathedral is an imitation of Hagia Sofia in Istanbul, and it was built in 1906-07 with the great contribution of Niko Nikoladze, the mayor of Poti. Notably, Niko Nikoladze chose the location of the cathedral in the center of the town to make it viewable from every side of Poti.
A. Zelenko and M. Marfeld were the architects of this Neo-Byzantine cathedral and the capacity of the church is 2,000 people. The ornaments and decorations are modeled after the medieval Christian cathedrals in the Trabzonmountains. The Poti Cathedral has three iconostases and among the main decoration of the iconostasis are the icons of St. Nino, St. Andrew the First Called, and the St. David the Builder.
This is one of the earliest examples of reinforced concrete applied to a church. The Hennebique system was employed following a project made by the office's engineers in Paris. Several projects were made, but because of the bad soil, a traditional solution in masonry was not adequate. So, the reinforced concrete was used for the foundations and the entire structure, domes comprised.
In 1923, after the Red Army invasion of Georgia, the Communist government turned it into a theater and the bells were donated to the industrialization foundation. In 2005, the cathedral was restored to the Georgian Orthodox Church.References:
Ängsö Castle was first named as "Engsev" in a royal charter by king Canute I of Sweden (r. 1167-1196), in which he stated that he had inherited the property after his father Eric IX of Sweden. Until 1272, it was owned by the Riseberga Abbey, and then taken over by Gregers Birgersson.
From 1475 until 1710, it was owned by the Sparre family. The current castle was built as a fortress by riksråd Bengt Fadersson Sparre in the 1480s. In 1522, Ängsö Castle was taken after a siege by king Gustav Vasa, since its owner, Fadersson's son Knut Bengtsson, sided with Christian II of Denmark. However, in 1538 it was given by the king to Bengtsson's daughter Hillevi Knutsdotter, who was married to Arvid Trolle.
In 1710, the castle was taken over by Carl Piper and Christina Piper. Ängsö Castle was owned by the Piper family from 1710 until 1971, and is now owned by the Westmanna foundation. The castle building itself was made into a museum in 1959 and was made a listed building in 1965. It is currently opened to visitors during the summers.
The castle is a cubical building in four stores made by stone and bricks. The lower parts is preserved from the middle ages. It was redecorated and expanded in the 1630s. The 4th storey as well as the roof is from the expansion of Carl Hårleman from 1740-41. It gained its current appearance in the 1740s.
