Успенский кафедральный собор, Orthodox cathedral under construction in Ulan-Ude, Russia

The Assumption Cathedral is a two-storey church with a basement in Oreshkov Park, designed by architect Sergey Lukiyanov with elements of classicism, baroque and Moscow Russian architecture. Its five domes rise to 53 m at the central cross, while the bell tower reaches 61.5 m. The total area is about 2,780 m², with four side chapels on the upper floor and a library, Sunday school, hall and refectory below.

Construction began in 2011 when the first stone was laid in a city park, with architect Sergey Lukiyanov designing a plan that merged different styles to reflect local traditions and European influences. A church community was officially formed in 2013 to oversee the project, which proceeded with modern materials and techniques to ensure the building would serve future generations of worshippers.

The name honours the Dormition of the Mother of God, the feast the church was consecrated to by decision of Patriarch Kirill. The parish of the Assumption Cathedral was formed by early 2013, before full-scale building work started. The design mixes classicism, baroque and Moscow Russian architecture, and a model of the five-domed church was displayed in the upper chapel of the Svyato-Odigitriyevsky Cathedral.

The cathedral is being built in Oreshkova Park on Prospekt 50-letiya Oktyabrya in the Zheleznodorozhny district, on a 2,500 m² plot; the project also provides for landscaping 4,500 m² of the surrounding park. The site is an active construction zone, so access to the building itself may be limited. A parking area is planned as part of the project.

The first foundation stone was laid on 28 April 2011 and consecrated by Metropolitan Varsonofy of Saransk and Mordovia. Patriarch Kirill chose the dedication to the Dormition of the Mother of God. A scale model of the five-domed church was displayed in the upper chapel of the older Odigitrievsky Cathedral.
