At least one-fifth of the Netherlands’ 6,900 church buildings have been converted for secular use, a national Dutch newspaper reports ― and hundreds more are expected to follow suit in the coming years. About 25% of Dutch churches built between 1800 and 1970 are now being used for nonreligious purposes, including as apartment complexes, offices and cultural centers, according to an investigation published by the Trouw in June. Around 20% of Dutch churches built before 1800 have also been redesigned, most often finding new life as community centers, museums or theaters. Dutch church buildings are often located in central areas, Trouw reports. Old church buildings can be expensive for a dwindling congregation to maintain. Churches built before 1800 are often considered national monuments. All of this means that deciding how to repurpose these old buildings while maintaining their cultural legacy has become a key topic of concern for local communities.

Trouw’s investigation into converted church buildings comes during a time of increased secularization in Dutch society. In 2017, the number of religiously unaffiliated people in the Netherlands surpassed the number of religious folk for the first time in history (51% vs. 49%), according to government data. Many formerly religious Dutch people say they left their religion because they no longer believe in its teachings, according to the Pew Research Center. A significant number also claimed they just “gradually drifted away.” Simon Richter, a professor of Germanic languages and literatures at the University of Pennsylvania, said he believes the trend toward secularization in the Netherlands is connected to increased quality of life for broad swaths of the population, high levels of education and “a general sense that human rationality can get you pretty far.” “The drift away from the church set in during the ’60s and hasn’t let up —we’re talking at least three generations of resolute drift in the meantime,” Richter wrote in an email. The Catholic Church, which has a stronger presence in the Netherlands than Protestant denominations, has also been facing a serious priest shortage, according to Jeroen Dewulf, a professor of Dutch studies at the University of California, Berkeley’s Institute of European Studies. “Many churches have been standing empty for years and they are so costly to maintain that alternative destinations for these churches have been sought,” Dewulf told HuffPost. Another reason for the emptying churches is Netherlands’ religious history, according to Hans Oosterhoff, a minister in the Protestant Church in the Netherlands, the country’s largest Protestant denomination. For example, he said there were many divisions between Protestant denominations in the Netherlands in the 19th century, which meant members prioritized worshipping in the churches of their specific denominations. These old denominations are now uniting, Oosterhoff said, meaning the churches members built previously are becoming redundant. “While secularisation is the main cause of churches becoming superfluous, there can be many different reasons why this or that church is being sold or demolished,” Oosterhoff wrote in an email.
