The Holy Trinity Cathedral (known as Sameba) is the main cathedral of the Georgian Orthodox Church located in Tbilisi. Constructed between 1995 and 2004, it is the third-tallest Eastern Orthodox cathedral in the world and one of the largest religious buildings in the world by total area. Sameba is a synthesis of traditional styles dominating the Georgian church architecture at various stages in history and has some Byzantine undertones.
The Sameba Cathedral is erected on the Elia Hill, which rises above the left bank of the Kura River (Mtkvari) in the historic neighborhood of Avlabari in Old Tbilisi.
The cathedral consists of nine chapels (chapels of the Archangels, John the Baptist, Saint Nino, Saint George, Saint Nicholas, the Twelve Apostles, and All Saints); five of them are situated in a large, underground compartment.
The Sameba complex, the construction of which is already completed, consists of the main cathedral church, a free-standing bell-tower, the residence of the Patriarch, a monastery, a clerical seminary and theological academy, several workshops, places for rest, etc.
References:Celje Castle was once the largest fortification on Slovenian territory. The first fortified building on the site (a Romanesque palace) was built in the first half of the 13th century by the Counts of Heunburg from Carinthia on the stony outcrop on the western side of the ridge where the castle stands. It had five sides, or four plus the southern side, which was a natural defence. The first written records of the castle date back to between 1125 and 1137; it was probably built by Count Gunter. In the western section of the castle, there was a building with several floors. Remains of the walls of this palatium have survived. In the eastern section, there was an enclosed courtyard with large water reservoirs. The eastern wall, which protects the castle from its most exposed side, was around three metres thicker than the rest of the curtain wall. The wall was topped with a parapet and protected walkway.
