Stone church, long church with end tower. Mikkeli Cathedral is a long church with end tower built of exposed brick. The former city congregation's church represents typical neo-Gothic from the late 19th century. The polygonal choir at the east gable is narrower and lower than the nave. The west tower is square. The church's long sides are articulated by cross-gables above the round-arched windows. The central nave of the church's nave has a wooden vault; the side aisles separated by the colonnade and side galleries have flat ceilings. The church's altarpiece is Pekka Halonen's The Crucifixion from 1899. Monumental granite steps descend from the surrounding park down toward Hallituskatu.
