"The sacristy door of the Biertan Fortified Church is internationally renowned for its complex system of 19 locks made by local craftsmen in 1515, the Mangalia News reports.


"The master Johannes Reichmuth from Sighişoara built, around 1515, the door of the sacristy of the fortified church from Biertan (the sacristy room housed the treasure of the church and the local community, during the siege). The door lock system activated 19 locks at a time by turning a key.


"The 19 locks are divided as follows: 3 on the left, 3 on the right, 3 on top and 7 on the actual lock, all operated simultaneously with a single key. This lock still works today, being a representative example of medieval Saxon manufacture, thanks to its exceptional woodwork ornaments and the original closing system."

The World's most complicated church lock was displayed at the 1889 Paris World's Fair.


"This jewel of medieval technology can be considered the early version of a Rube Goldberg machine, which in this case also has a functional role," said Ramona Nita, News editor at the  World Record Academy.

The church has three rows of exterior fortifications linked by gate towers, nine in total.


The first, with four towers, dates to the 14th century; the second was built together with 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.

One of the most attractive elements for visitors is the sacristy door, which due to its uniqueness was awarded at a Parisian exhibition in 1910. Dated from 1515 and made of oak with beautiful inlays, it also has the master Johannes Reichmut as its maker. the author of the pews.


The uniqueness of this piece also contributed to the complicated locking system operated by a wrench and a crank. Four mechanisms are activated by the key and another fifteen by the crank. In the event of a siege, all the valuables of the community were housed here. The late Gothic style baptismal font is made of stone and dates back to the 16th century. It is decorated with lily flowers and is partially buried in the floor.

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.

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.
