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:
Angelokastro is a Byzantine castle on the island of Corfu. It is located at the top of the highest peak of the island"s shoreline in the northwest coast near Palaiokastritsa and built on particularly precipitous and rocky terrain. It stands 305 m on a steep cliff above the sea and surveys the City of Corfu and the mountains of mainland Greece to the southeast and a wide area of Corfu toward the northeast and northwest.
Angelokastro is one of the most important fortified complexes of Corfu. It was an acropolis which surveyed the region all the way to the southern Adriatic and presented a formidable strategic vantage point to the occupant of the castle.
Angelokastro formed a defensive triangle with the castles of Gardiki and Kassiopi, which covered Corfu"s defences to the south, northwest and northeast.
The castle never fell, despite frequent sieges and attempts at conquering it through the centuries, and played a decisive role in defending the island against pirate incursions and during three sieges of Corfu by the Ottomans, significantly contributing to their defeat.
During invasions it helped shelter the local peasant population. The villagers also fought against the invaders playing an active role in the defence of the castle.
The exact period of the building of the castle is not known, but it has often been attributed to the reigns of Michael I Komnenos and his son Michael II Komnenos. The first documentary evidence for the fortress dates to 1272, when Giordano di San Felice took possession of it for Charles of Anjou, who had seized Corfu from Manfred, King of Sicily in 1267.
From 1387 to the end of the 16th century, Angelokastro was the official capital of Corfu and the seat of the Provveditore Generale del Levante, governor of the Ionian islands and commander of the Venetian fleet, which was stationed in Corfu.
The governor of the castle (the castellan) was normally appointed by the City council of Corfu and was chosen amongst the noblemen of the island.
Angelokastro is considered one of the most imposing architectural remains in the Ionian Islands.
