The first records of a chapel in Birgsau date back to 1680. At that time, it was a small wayside chapel dedicated to the Virgin Mary.

Construction of the chapel began in 1846 but, due to difficulties, was not completed until two years later. The interior was designed by craftsmen and artists from Oberstdorf. In 1848, the little church was consecrated as the Wendelins-Kapelle (Wendelin Chapel)

However, the present-day altar with its paintings dates from 1938. In choosing the colours, the artist took particular care to use the original colours of local flowers.
