Berlin's churches urged to open as heatwave shelters amid rising temperatures

Berlin and Brandenburg’s Catholic and Protestant churches have urged their congregations to open their buildings as cool spaces during heatwaves. With temperatures rising, only a small number of churches currently remain accessible to the public for heat relief. The call comes as Berlin faces criticism over a lack of cool public spaces. The Left Party and Green Party have pressed the Senate to explore alternatives, including opening air-conditioned art museums and exhibition halls free of charge.

Many churches stay naturally cool due to their thick walls and high ceilings. However, most remain locked because of concerns about theft, vandalism, and liability. Financial constraints also limit how often congregations can open their doors, often relying on volunteers to keep spaces available.

A few churches already serve as heat refuges. Apostle Paul Church in Schöneberg stays open daily year-round, supported by local volunteers. St. Mary’s Church near the TV Tower remains accessible every day, funded by tourist donations and offering shelter to marginalised groups. Wichern Church in northern Spandau also welcomes residents seeking relief from extreme temperatures.

Despite the potential, only 13 out of around 400 Protestant churches and chapels in Berlin are open every weekday for this purpose. The initiative highlights the role churches could play in providing cool spaces during heatwaves. Without additional funding or support, however, most will remain closed. The debate continues over how the city can better address the demand for accessible, temperature-controlled public areas.
