the church, and has a series of reinforcing arches; the third, also with towers, is from the 16th and 17th centuries. The clock tower to the north of the church also serves as a gate within the inner fortifications. Four stories high, it has a wooden battlement and parapets. The clock is above the pyramid-shaped roof. The wooden bell tower is located north of the church, while the mausoleum tower contains the headstones of the priest who built the church as well as the bishops buried at Biertan. The Catholic tower was used by the few Saxons who did not adhere to the Reformation but kept their Roman Catholic faith. Its chapel (ca. 1520–1530) features a rare example of 16th-century Transylvanian mural painting, forming an exception to the austere aesthetic that predominated. The grounds contain a "matrimonial prison" where couples wishing to divorce were confined so they could be sure they wished to end their marriage. The lockup lasted for two weeks, although the pair could leave early if they reconciled. They had to share a single bed, plate and spoon. During the three centuries that bishops resided at Biertan, just one couple ended up divorcing. The church was occupied and robbed in 1704, during Rákóczi's War of Independence. It suffered damage during the 1977 Vrancea earthquake and subsequently underwent restoration work between 1983 and 1989. Since 1990, Saxons come annually to Biertan to celebrate their heritage. In 1993, Biertan and its fortified church were declared a UNESCO World Heritage Site; it was joined by six other places in 1999 to form the villages with fortified churches in Transylvania site. Additionally, the church is listed as a historic monument by Romania's Ministry of Culture and Religious Affairs, with each of the three fortifications considered a separate monument. Biertan was the subject of two 2011 postage stamps, a joint issue between Germany and Romania.
