Tsminda Sameba (in translation from the Georgian “Holy Trinity”) is the main cathedral of the Georgian Orthodox Church, built to the 2000 anniversary of the birth of Christ on the hill of St. Ilya in the center of Tbilisi. The Cathedral of Tsmind Sameba, called the “Millennium Building”, is the third tallest Orthodox church in the world. The construction of the temple took place for charitable donations of the inhabitants of the country and lasted 9 years (1995-2004). The height of the cathedral is 98 meters, the area is more than 5000 square meters, and the capacity of 15000 parishioners. After consecration in the temple of Sameba from the Zion Cathedral, the Department of Catholicos of Georgia is postponed. The complex of Tsminda Sameba today consists of the main cathedral, a separate bell tower, the residence of a patriarch, a monastery, a clerical seminary, the Theological Academy and places for recreation. The cathedral has nine chapels. Five of them are located in the underground part of the building, leaving 13 m below ground level. Today the Cathedral of Sameba, towering on the hill of St. Ilya on the left bank of the Kura, is visible from anywhere in the city.
