People's Salvation Cathedral in the context of "Eastern Orthodox Christianity"

Eastern Orthodoxy, otherwise known as Eastern Orthodox Christianity or Byzantine Christianity, is one of the three main branches of Chalcedonian Christianity, alongside Catholicism and Protestantism. Like the Pentarchy of the first millennium, the mainstream (or "canonical") Eastern Orthodox Church is organised into autocephalous churches independent from each other. In the 21st century, the number of mainstream autocephalous churches is seventeen; there also exist autocephalous churches unrecognized by those mainstream ones. Autocephalous churches choose their own primate. Autocephalous churches can have jurisdiction (authority) over other churches, some of which have the status of "autonomous" which means they have more autonomy than simple eparchies.

Many of these jurisdictions correspond to the territories of one or more modern states; the Patriarchate of Moscow, for example, corresponds to Russia and some of the other post-Soviet states. They can also include metropolises, bishoprics, parishes, monasteries, or outlying metochia corresponding to diasporas that can also be located outside the country where the primate resides (e.g., the case of the Ecumenical Patriarchate of Constantinople whose canonical territory is located partly in northern Greece and the east); sometimes they overlap (the case of Moldova where the jurisdictions of the patriarchs of Bucharest and of Moscow overlap).

The Orthodox Cathedral (Romanian: Catedrala Ortodoxă), also known as the Metropolitan Cathedral (Romanian: Catedrala Mitropolitană), is a Romanian Orthodox church in Timișoara. The cathedral is the seat of the Archbishopric of Timișoara and the Metropolis of Banat. It is dedicated to the Three Holy Hierarchs, Basil the Great, Gregory the Theologian and John Chrysostom.

Built on an area of 1,542 m, it has 11 towers, of which the central one has a height of 90.5 m, making it the second tallest church in Romania, after the People's Salvation Cathedral in Bucharest. The cathedral is listed in the National Register of Historic Monuments.

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.

This list of tallest church buildings ranks church buildings by height. From the Middle Ages until the advent of the skyscraper, Christian church buildings were often the world's tallest buildings. From 1311, when the spire of Lincoln Cathedral surpassed the height of the Great Pyramid of Giza, until the Washington Monument was completed in 1884, a succession of church buildings held this title.

• The tallest church building in the world is the Sagrada Família in Barcelona, which surpassed Ulm Minster (161.53 m) on 30 October 2025 when its central tower reached 162.91 m. The tower is intended to reach 172 m when completed, expected in 2026.
