Dârjiu fortified Unitarian Church is a historical and architectural monument from the 13th-14th centuries, one of the six fortified churches in Transylvania included in 1999 in the UNESCO list of world cultural heritage. The Church represents one of the most important fortified Saxon churches, present in all the references to such monuments in Transylvania due to the mural paintings inside the church (mostly destroyed) but also to the architecture of the fortifications surrounding it. The Church stands on an ancient Roman Basilica dating back to the 13th century.
Raising the current building began in the 14th century and finished in the 15th century, the fortifications being erected in the 16th century, which included five bastions, bell-towers and defensive walls of stone. The church acquired its present shape in the late 15th century, when an extension in Gothic style was made. Particularly valuable are the frescoes representing the legend of St. Ladislas, dating back to the time prior the Protestant Reformation. These murals were covered during the Reformation and were rediscovered in the 19th century.
The church tower, which lies south of the church itself is the oldest part of the fortification system. The wall of the church served as defense against Ottoman attacks, but not as high as the Saxon fortified churches, as the village itself is located high enough. The wall has two gates, so that Turks who once entered the first gate were stuck within the enclosure and burned with hot tar.
