Christ the King Cathedral, Belo Horizonte, Metropolitan Cathedral in Belo Horizonte, Brazil.

Christ the King Cathedral is an unfinished Catholic cathedral on Cristiano Machado Avenue in northern Belo Horizonte. Its exposed concrete skeleton forms a rectangular grid of columns and slabs, with a broad flat roof area and a tall lattice crane beside it. Two 100-metre portals, named Truth and Justice, are designed as hands in prayer.

Bishop Antônio dos Santos Cabral chose Christ the King as patron when he installed the diocese in 1922, and the first site proposed was Milton Campos Square. The plot on Cristiano Machado Avenue was later chosen. Archbishop Walmor Oliveira de Azevedo commissioned Oscar Niemeyer in late 2005; he finished the project in 2006, and work funded by donations began in 2013. On 11 February 2021 the still-unfinished temple was officially given the title of cathedral.

The name Cristo Rei comes from the dedication chosen by Bishop Antônio dos Santos Cabral, who arrived in 1922 to install the diocese. The 100-metre-high portals of Truth and Justice are designed to resemble hands joined in prayer. Masses and guided tours have been held at the construction site.

The building sits in the northern part of Belo Horizonte on Cristiano Machado Avenue and is accessible by public transportation. Be aware that construction work continues on the structure, so some areas may have limited access.

The 100-metre-high portals of Truth and Justice are designed as hands joined in prayer, and the nave sits on the third of three floors. The site covers 24,000 square metres, with 44,000 square metres of built area including three levels below the plaza and parking. The cathedral is planned for 5,000 seated worshippers and up to 20,000 at larger events.
