Eastern Orthodox church architecture in the context of "List of Byzantine inventions"

Sts. Cyril and Methodius Church (Serbian: Храм светих Кирила и Методија/Hram svetih Kirila i Metodija, Slovene: Cerkev sv. Cirila in Metoda), commonly known as the Orthodox Church (Slovene: Pravoslavna cerkev, Serbian: Pravoslavna crkva), is an Eastern Orthodox church building located in Trubar Park (Slovene: Trubarjev park), between Bleiweis Street (Bleiweisova cesta) and Prešeren Street (Prešernova cesta), north of the Museum of Modern Art and west of the National Gallery of Slovenia. It belongs to the Metropolitanate of Zagreb and Ljubljana of the Serbian Orthodox Church and is named after Saints Cyril and Methodius, brothers known as the "Apostles to the Slavs."

Built in Serbo-Byzantine Revival, the church has five domes with golden crosses at their top. It was built from 1932 to 1936 by Ivan Bricelj based on plans by the architect Momir Korunović. The frescoes in the interior were painted by the Serbian painters Dragomir Jašović, Miša Mladenović, and Danica Mladenovič from 1986 until 1997. The iconostasis is work of a prominent woodcarver workshop from Debar (Macedonia) and has been decorated with icons by the Slovene painter Mirko Šubic [sl], who created them in 1940.

In architecture, a pendentive is a constructional device permitting the placing of a circular dome over a square room or of an elliptical dome over a rectangular room. The pendentives, which are triangular segments of a sphere, taper to points at the bottom and spread at the top to establish the continuous circular or elliptical base needed for a dome. In masonry the pendentives thus receive the weight of the dome, concentrating it at the four corners where it can be received by the piers beneath.

Prior to the pendentive's development, builders used the device of corbelling or squinches in the corners of a room. Pendentives commonly occurred in Orthodox, Renaissance, and Baroque churches, with a drum with windows often inserted between the pendentives and the dome. The first experimentation with pendentives began with Roman dome construction in the 2nd–3rd century AD, while full development of the form came in the 6th-century Eastern Roman cathedral, Hagia Sophia, in Constantinople (Istanbul).

Dealul Spirii (Romanian: [ˈde̯alul ˈspirij], Spirea's Hill) is a hill in Bucharest, Romania. It is the location of the Palace of the Parliament, initially built by Nicolae Ceaușescu as the House of the People, and the National Cathedral of Romania, also the People's Salvation Cathedral - the largest Eastern Orthodox church in the world.

The soleas ((Greek: σολέα, other form σολέας) = Latin: solea meaning (“bottom, base”, as used in "sole of a shoe", cf. also the "sole" from the resemblance of fish to a flat shoe. Of uncertain origin)) is an extension of the sanctuary platform in an Eastern Orthodox temple (church building). The soleas projects beyond the iconostasis, forming a narrow walkway running the full length of the iconostasis.

In the center of the soleas is the ambon, directly in front of the Holy Doors, where the communicants stand to receive Holy Communion and where the clergy come out for public prayers, sermons, etc.
