and with the adhesive 10 tons. The iconostasis is covered with mosaic on both sides, having 800 square meters of mosaics, and is made of reinforced concrete with a thickness of 1.26 meters. The royal gate has an inner vaulted of 4.28 meters height with 2.50 meters width, the edge of the gate being covered with 12.4 tons of Onyx stone. Age-old since the world began, the onyx is the first gemstone which find in the pages of the Old Testament, in the Garden of Eden (Genesis 2:12). For the realization of the iconostasis of the cathedral in Bucharest, a team of over 45 mosaic and fresco specialists worked for ten months. The leader of this team was iconographer Daniel Codrescu. Originally, the team had thought of marble frames for each large icon, but because the weight of the material could have affected the structure of the iconostasis resistance, the idea was abandoned. This iconostasis is made entirely of mosaic and fresco in Byzantine style. The team involved in the project was divided into two groups: the first involved in making the mosaics in the workshop, and the second in fitting them on the stonework. A source of inspiration was the famous mosaics in Ravenna, represented by the Basilica of San Vitale. Iconographer Daniel Codrescu said: "Everything is worked in the smallest details. The team tried to take the realization to another level of greatness. With the help of God, this monumental work is a gift to the Centenary of Romania. This iconostasis is the summary of the kingdom of heavens." The front of the iconostasis has 45 icons placed on four registers. The first register has six royal icons, the second register has thirteen icons with royal feasts, the third register has the icon of the Holy Trinity (center) and the twelve Apostles, and the fourth register has the Theotokos (center) and the twelve Prophets of the Old Testament. On the four side doors are the four archangels, and on the royal door are the Annunciation and the four Evangelists. The royal icons have the dimensions of 2.15 meters width with 3.75 meters height and an area of 8 square meters. All icons of the iconostasis have a total of 130 portraits. The rear face of the iconostasis contains three registers. The upper register in the center contains the Last Supper, represented by the liturgical variant in the hemicycle
