The church was constructed between 1974 and 1976, commissioned by the Archdiocese of Vienna.
Fritz Wotruba designed the structure to symbolize a 'living' form rather than a static religious building.
The 152 concrete blocks were positioned with mathematical precision to allow natural light to filter through the cracks throughout the day.
The church is located on the highest point of the Georgenberg in the Mauer district, providing a clear view over the Vienna Woods.
Despite its unconventional exterior, the church was consecrated in 1976 and is fully functional for liturgical services.
The internal acoustics are stark and minimalist, reflecting the heavy concrete surface area.
The Wotrubakirche, officially the Church of the Most Holy Trinity, is a brutalist structure composed of 152 asymmetrical, raw concrete blocks ranging from 1.8 to 141 tons. Designed by sculptor Fritz Wotruba and architect Fritz G. Mayr, the building serves as a permanent architectural sculpture integrated into the landscape of the Georgenberg hill. The project was completed in 1976, four years after Wotruba's death. It lacks a traditional facade or interior symmetry, with light entering through irregular gaps between the stacked concrete blocks. The structure occupies a site formerly home to a Nazi-era Wehrmacht barracks. The altar is carved from a single block of white marble, contrasting with the grey concrete surroundings. It remains an active Catholic parish church serving the 23rd district of Vienna.
The path leading up to the church entrance, where the silhouette of the stacked blocks is most visible against the sky.
Wear sturdy walking shoes to navigate the steep path from the base of the hill to the church entrance.
Check the parish calendar before visiting, as the church is frequently closed to tourists during private religious ceremonies or weddings.
Bring a light jacket as the concrete structure remains significantly cooler than the ambient outdoor temperature.
Do not expect a traditional cathedral layout; the interior is small and lacks seating aisles, which can be disorienting.
The church is primarily open for guided tours on specific weekend days; check the official parish website for seasonal availability.
Maintain silence as this is an active place of worship; photography is permitted but avoid using flash during services.
