The Fortified Church of Boz (Biserica Fortificată din Boz) is a historic Lutheran church and fortified enclosure in the village of Boz, part of Doștat commune in Alba County. Built in 1523, the late Gothic hall church was designed from the beginning to serve both religious and defensive purposes.
The church replaced an earlier Romanesque building and was constructed almost entirely of brick. Its nave and choir form a continuous hall of similar width, covered by a decorative ribbed vault, while stepped buttresses reinforce the exterior walls.
What makes Boz especially distinctive is the two-level defensive structure built directly above the church. The lower level was equipped with openings between the supporting consoles, while the upper level contained firing positions. Both defensive floors could be reached by a spiral staircase on the northeastern side, turning the church itself into the strongest part of the complex rather than relying mainly on an outer wall.
The church was surrounded by a fortified enclosure, of which a low ring wall and northern gatehouse still survive. The gatehouse retains part of the former wall walk, while another defensive building in the complex was later reused as a school and residence.
Inside, the decoration is relatively restrained. The main altar dates from the early Baroque period, while most of the remaining furnishings belong to the 19th century. The contrast between this simple interior and the unusually elaborate defensive structure above it is one of the defining characteristics of the church.
