Designed by Karl Moser the Antoniuskirche in Basel was built between 1925 and 1927 as the first pure concrete church in Switzerland. One of the most striking features of the Antoniuskirche is its use of concrete, a material that was then considered avant-garde in ecclesiastical architecture. The decision to use concrete not only allowed for new architectural possibilities but also aligned with modernist ideals of simplicity and functionality, its almost austere aesthetic contrasting with the ornate decoration typical of older church designs. Interestingly the consecration was delayed until 1931: rumour has it this was due to its extremely modern look, while the official reason were the not yet paid building costs.
While the church has a height of 22 meters, the tall, free-standing bell tower rises 62 meters high. The church’s facade is minimalistic, dominated by vertical lines.
The nave offers an unobstructed view of the altar. This open plan was made possible by the use of concrete, which allowed for a wide span without the need for many supporting pillars. The colourful windows were designed by Hans Stocker and Otto Staiger.
