Amidst the picturesque valley of Hârtibaciu river lays the village of Hosman. The fortified church in the center of the settlement is one of the most photographed motives in all of Transylvania. In clear weather the church has as background the spectacular view of the often snow-caped Făgăraşi mountains.
The church's name comes from a nickname given to it after a city-wide fire broke out in 1689 and blackened the church's walls. The church houses several notable artworks including 15th-century paintings, and 17th - 18th-century Ottoman rugs. The church also houses two exhibitions, one about the history of the church, and the other about the life of Johannes Honterus, an important figure in the Protestant Reformation of Transylvania.
The fortified church of Prejmer was built in the 13th century on the site of an old Romanesque church dating from the 12th century. Located near the Buzău pass, used to enter Transylvania, Prejmer was particularly affected by the first Ottoman escursions on this territory in the 15th century. Thus, the church was heavily fortified in the 16th century. Extremely well preserved, the church was inscribed on UNESCO's World Heritage List in 1999.
