St. Sebastian's Cathedral, Bratislava, Roman Catholic cathedral in District of Bratislava III, Slovakia.

St. Sebastian's Cathedral is a modern religious building with clean architectural lines and geometric forms located in northern Bratislava. The structure showcases contemporary design with functional layouts that serve its specific purpose as a military chapel.

Planning for this cathedral began in 1995, though construction work did not start until 2007. Archbishop Stanislav Zvolenský consecrated the completed building in 2009, marking its inauguration as one of the city's newer sacred structures.

The cathedral serves as the principal church of the Catholic Military Ordinariate of Slovakia, functioning as a spiritual center for military personnel and their families. Its role within the military community shapes how the space is used and experienced throughout the week.

The cathedral stands in Bratislava-Krasňany, in the Bratislava III district, at the northern edge of the city. It is the seat of the Catholic Military Ordinariate of Slovakia, so some services are tied to the armed forces rather than to a parish. Check the ordinariate's own listings before planning a visit.

The cathedral is dedicated to Saint Sebastian, who is also the patron saint of Slovakia's military ordinariate. Before it took over this role, the ordinariate's temporary main church from 2003 to 2009 was the Cathedral of Saints John of Matha.
