Exterior The church is centrally planned edifice, having the form of a
Greek Cross. It has a large central dome supported on four
pendentives and
buttressed on each side by a lower
semi-dome over an
apse. Beneath each semi-dome is a gallery supported on an arcade. The general concept is heavily based on the
Hagia Sophia. Its main construction idea stems from the central square beneath the dome, it is closely related to the geometry used by
Isidore of Miletus and
Anthemius of Tralles. The central square in both churches has sidelines of 31 m, resulting in domes with approximately the same diameter (the dome of Hagia Sophia is slightly larger as it extends by approximately 0,5 the central square). The main differences in the dome structure is the high
tambour in Saint Sava and that it is double-shelled. The low dome of Hagia Sophia was designed as calotte in which base 40 windows were set. As thus, both domes are built on pendentives at 40 m height, the dome of Saint Sava is approximately 10 m higher (54 to 67 m). The naos of the church is 46 m wide and 46 m long. The church interior has narthexes on three sides of which two have 9 m depth and 31,70 m width. Within the north and south narthex two small chapels will be created. The narthex to the main entrance in the west is 2 m longer and has four more columns than the other two. Above the narthexes are three galleries with that of the west side assigned to the church choir. As of 2019 the marble iconostasis is in work and will have six main icons and three doors. On the left and right sides of the iconostasis are bishopric seats. The facade of the church was mainly executed in white marble. It covers 12.000 m2. The polished Grecian Volakas marble from Kavalla took 14 months to install. Cornices are made of red Balmoral granite from Finland. It covers 120 m2 on the dome and the half-domes. The pedestal is made of 80 m2 black Jablanica granite from Bosnia. The stones in the facade weigh 3.000 tonnes. The
dome is high, while the main gold-plated cross is another high, which gives a total of to the height Church of Saint Sava. The peak is above the sea level ( above the
Sava River); therefore the church holds a dominant position in Belgrade's
cityscape and is visible from all approaches to the city. The church is long from east to west, and from north to south. It is tall, with the main
gold-plated cross extending for more. Its
domes have 18 more gold-plated crosses of various sizes, while the
bell towers have 49
bells of the Austrian Bell Foundry
Grassmayr. The church has a bigger floor area than
Cathedral of Christ the Saviour in Moscow, which covers 3980 m2, compared to 4500 m2 of Saint Sava. Saint Sava is also longer 91 m vs 77,7 m and wider 81 m vs 72,42 m, it also has a bigger diameter of its dome 30,5 m vs 25 m. The dome of the Moscow cathedral is higher so, 77,37 m vs 103,4 m. Interestingly, both cathedrals resemble the Hagia Sophia in its structural design, they've been designed based on the arrangement of the central square in the Hagia Sophia. Thus they exemplify the importance of the imperial Byzantine church for main edifices in Orthodox sacral architecture. On the inspiration that was drawn from Hagia Sophia, Deroko noted that two guiding principles were followed in designs for the Church of Saint Sava – the imperative of functionality of planning, and the monumentality of space and form. Looking back at the start of construction, Deroko commented on the challenges of designing a functional space for 10.000 people, which was done with reference to the architects' data, the seminal handbook by
Ernst Neufert. He also noted information about the thirty-metre diameter of the dome, making an obviously important comparison with the dome of Hagia Sophia. Although the size of Saint Sava is not necessarily associated with monumentality in Deroko's opinion, the appearance and size of the St. Sava's church greatly mattered as it was to be a monument of national importance.

Dome The dome of Saint Sava is built in the classical style as a compound dome with four pendentives from a sphere of greater radius than the dome. It has an inner diameter of 30,50 m and an outer of 35,15 m, resembling the dimensions of the
Hagia Sophia (it had initially a realized diameter of 33 m). The double-shelled dome is 27 m high and reaches to 67 m on the outside and on its inner side to 64,56 m height. Thus the dome of Saint Sava is slightly higher than its archetype of the Hagia Sophia (56 m). The dome supports a cross designed by Nebojša Mitrić and Pešić 12m in height and 5m in width. After the Hagia Sophia, the dome of Saint Sava is the biggest in any Orthodox church. The celebrated dome of the Hagia Sophia, built by
Isidore of Miletus and mathematician
Anthemius of Tralles, was initially at 33 m which was reconstructed from the mathematical formulas used by its Byzantine architects. Today, after having been rebuilt three times, it has an elliptic form with the diameters 31.24 m and 30.86 m. Among all Christian religious buildings, the pendentive domes of
Hagia Sophia (33 m, initially realized diameter),
St Paul's Cathedral (30.8 m),
Florence Cathedral (43 m),
St. Peter's Basilica (42 m),
Berlin Cathedral (30.7 m), and
Primatial Basilica of the Blessed Virgin Mary (33 m) have larger or approximately the same inner diameters to Saint Sava's. Other than Hagia Sophia, none of them were built on four piers and with four vaults. Among the mentioned domes, Saint Sava's has 24 m-wide vaults, only surpassed by Hagia Sophia's (31 m). The much bigger dome of St. Peter's Basilica has main vaults of only 23 m. If compared to the biggest domes realised in Orthodoxy, Saint Sava surpasses by large the
Cathedral of Christ the Saviour in Moscow, whose dome has 29.8 m (outer) and 25 m (inner) diameters, the
Kronstadt Naval Cathedral with 29.8 m (outer) and 26.7 m (inner) diameters and the
Saint Isaac's Cathedral in Saint Petersburg with 25.8 m (outer) and 21.8 m (inner) diameters. In addition to its big diameter, the dome of Saint Sava has significant interior height as well. With 65 m (from the floor to the ceiling) it is the fourth-tallest dome (by interior height) of Orthodox Christianity, surpassed only by the domes of
People's Salvation Cathedral in
Bucharest (104 m),
Cathedral of Christ the Saviour in
Moscow (69.5 m) and
Saint Isaac's Cathedral in
Saint Petersburg (69 m). The dome of Saint Sava also ranks among
the tallest domes in the world.
Interior The interior with naos, three side arms and the altar has a surface area of on the
ground floor, with three
galleries of on the first level, and a gallery on the second level. The church can hold 10,000 faithful. The
choir gallery seats 800 singers. The basement contains a
crypt, the
treasury of Saint Sava, and the grave church of
Saint Lazar the Hieromartyr, with a total surface of . The church will offer a permanent exhibition about the construction of the church, a bell information gallery and one that informs on the life of Saint Sava. At the northeastern and southeastern pillar, two elevators are being installed to reach the dome galleries. The northern and southern entrance halls have baptism fonts, a third at gallery level is on the northern side of the altar. The material of the sixteen great columns in the choir were imported from Italy in 1939. The capitals are made of Carrara marble, the columns by green marble from Baveno. The motifs of the capitals were designed by Aleksandar Deroko and were largely executed by Josif Grassi before WW II. The main iconostasis is made of iron trusses on which slabs of Carrara marble will be installed. The whole construction of the approximately 20 metre-wide iconostasis will weigh 100 tonnes. It will be decorated with mosaic icons. Work on the iconostasis as of August 20, 2020 was in progress. It will consist of one row of icons. The great central
wheel chandelier () is the main circular lightning device of the church, cast in bronze with a diameter of 20m. It is the greatest and heaviest in the world. It was designed by Nikolay Mukhin reminiscent of Serbian specimen of Dečani and Marko's Monastery. File:Иконостас_храма_Светoг_Саве_Сербског_у_Биограду,_Сербија.jpg|

Frescoes of the church
Mosaics Russian interest to contribute to the mosaic cladding became public during a 2009 visit of director of the Russian Academy of Arts Zurab Tsereteli.
Gazprom Neft was mentioned as sponsor. First assessments showed that 30 million Euros would be necessary for having all the interior done in mosaic cladding, and an initial donation of 4 million from Gazprom Neft allowed the first stage of works. Serbia and Russia agreed in March 2012 that a state competition be held in Moscow for the mosaic decoration, which took place at the gallery of the Russian Academy on 23 September 2014. The work of
Nikolay Mukhin (b. 1955), with classical 12th-century Palaiologos-era gold mosaics, was declared a winner on 5 October 2014 and his project was presented to the Serbian government and SPC representative Amfilohije. The central meeting discussing the implementation of works was held on 13 November 2015 in Belgrade.
Rossotrudnichestvo and its director, Lubov Nikolaevna Glebova, the designated Russian representative for the interior decoration, were present, as were the president of Serbia and its minister of foreign affairs. A second tranche over 5 million Euros was guaranteed personally by Vladimir Putin on 17 January 2019 during his visit to the church. All mosaics were commissioned in the Moscow atelier in their original size, then cut and transported to Belgrade. The first ten tonnes of mosaics arrived in Belgrade on 3 May 2017. The artists of the mosaics were chosen from the
Moscow School of Painting, Sculpture and Architecture in Moscow and the Repin Institute of Arts at the
Imperial Academy of Arts in Saint Petersburg.
Vladimir Putin of Russia visited the church in January 2019 and announced that the Russian state would finance parts of the remaining works in the mosaic cladding. He symbolically laid a stone in a mosaic with the presentation of the
Mandylion. The central mosaic in the dome depicts the
Ascension of Jesus and represents Resurrected Christ, sitting on a rainbow and right hand raised in blessing, surrounded by four angels, Apostles and
Theotokos. This composition is inspired by the mosaics in the main dome of
St Mark's Basilica in
Venice. The lower sections are influenced by the
Gospel of Luke and the first narratives of the
Acts of the Apostles. The texts held by the angels are written in the
Church Slavonic language, while the names of the depicted persons are written in Greek. The first indicates pan-Slavic sentiment while the latter connects it to the Byzantine traditions. The total painted area of the dome is . The dome is one of the largest curved areas decorated with the mosaic techniques and when the work is completely finished, Saint Sava will be the 6th-largest church building in the world ornamented this way after
St. Peter's Basilica in
Vatican City, the
People's Salvation Cathedral in
Bucharest (also unfinished), the
Basilica of the National Shrine of the Immaculate Conception in
Washington, D.C.,
Primatial Basilica of the Blessed Virgin Mary in Esztergom and
Berlin Cathedral. The mosaic was created for over a year in Russia, during 2016 and 2017. It was then cut and transported by special trucks to Belgrade. The total weight of the mosaic is 40 tons and it was placed on the dome from May 2017 to February 2018. The mosaic installed at the eastern wing section, the side of the altar covers 3,289 m2.
Sculptures Capitals and cornices show a variety of sculptures. The heraldic symbols of the
Nemanjić dynasty are a dominant motif. Floral motifs and anthropomorphic figures are inspired by the rich sculptural tradition of the
Morava school. The main author of the stone ornaments of the interior decoration was initially Aleksandar Deroko, whose plans were executed on all of the capitals at the columns between narthexes and naos and the altar apse. They were executed by the Swiss sculptor Josif Grassi prior to World War II. After the long delay during Socialist Yugoslavia, the decorative work was overseen by and executed by . A variety of different white marbles from Italy and Greece, green marbles from Italy, South America and India, dark and bright red marbles from Italy and India, yellow and greenish onyx, white limestone, red and white travertin and blue lapis lazuli. These decorative stones cover 1500 m2. == Plateau ==
