The Co-Cathedral of St. Alexander (Ukrainian: Співкафедральний собор св. Олександра ) also called Cathedral of St. Alexander of Kyiv is the name given to a religious building affiliated with the Catholic Church located in the city of Kyiv in Ukraine.
The church was built between 1817 and 1842 in a cruciform plan, with a dome at the intersection of the aisles in the style of classicism. The church is located on the former site of a Polish merchant's house and near Independence Square.[]
To commemorate the visit of Russian Tsar Alexander I in Kyiv the Polish owner Antoni Sawicki built, with the consent of the authorities, a wooden church on the site.[]
The first wooden church burned down in 1823; the new brick church was not completed until 1842. After 1905, the tsarist authorities eased restrictions on churches other than Russian Orthodox. In Soviet times a planetarium occupied the premises. After the fall of communism the building was renovated and became the co-cathedral of the Diocese of Kyiv-Žytomyr (Dioecesis Kioviensis-Zytomeriensis, Єпархія Київ-Житомир)[]
