The first parish church in Kożuchów was built in the mid-13th century, as a modest and small building in the north-western part of the then town center. The earliest mention of it comes from 1272, from the document of prince Henry III of Głogów. After being destroyed in a fire in 1339, it was rebuilt and enlarged at the same time. Further expansion was made at the end of the fourteenth and fifteenth centuries from the foundation of the dukes of Głogów, adding a chapel, sacristy and side aisle to the presbytery. Henry IX and his successor Henry XI were later buried in the newly created crypts of the chapels. After another fire in 1554, another renovation and reconstruction was needed. In 1725, the baroque Olives Chapel was added. In this century, after another fire, the temple gained new roofs and the top of the tower. The church survived the Second World War happily without major damages.
The original church from the 13th century was a small stone building consisting of a rectangular nave and a narrower rectangular chancel. In the fourteenth or even in the thirteenth century, from the north side of the presbytery, a four-sided tower was added.
The first major expansion from the fourteenth century was the widening of the brick nave by two aisles and construction of the the west porch and north chapel of All Saints at the end of that century. A southern aisle was also erected at the chancel and the sacristy attached to it. In the following century, chapels of the Holy Cross and All Saints, opened by arcades to the interior, were added to the northern aisle. In the second half of the fifteenth century, the church was enlarged with further chapels and a porch, this time added to the southern aisle. At the end of the fifteenth century, a new, larger sacristy was erected on the north side. It received a net vault, while the naves, presbytery and chapels were topped with rib vaults. In the mid-sixteenth century, the walls of the chancel were raised, aligning them with the walls of naves, and the whole church was covered with three parallel roofs.
