The pilgrim church of Holy Cross of Pietrowice Wielkie lies on the Wooden Architecture Trail of the Silesian province. It was built in 1667. It is a cabin log construction, and its gable roof is covered with shingles. Next to the nave and the chancel there is an outbuilding with a staircase leading the choir? The church has an outer pulpit with a canopy, a porch and a vestry. The belfry, built in 1822, is topped with a spherical helmet covered with tin sheets, a lantern and the papal cross. Along the east and north sides there are arcades, which in the past served as shelter for the pilgrims. The interior is decorated in the Baroque style. The high altar is adorned with a painting of Christ Crucified, and the side altars with Saint Anne and Our Lady of the Rosary.
