In 1485, Johannes Maurizius Tepesta constructed a chapel in Pontresina to pray to the Holy Spirit with Episcopal permission. It was only used for a short period and soon fell into oblivion. In 1941, remains of the former chapel were found in the basement rooms of the Haus Aebli, on the corner of Via Maistra and Via San Spiert. The current church has a turbulent history. It has undergone three construction phases in its 60-year history. In January 1923, the entire complex of the Restaurant-Casino Tais – consisting of a restaurant, a casino hall and a stable built underneath it – was purchased.While the restaurant was still operating, the hall was converted into a church and as early as 15 July, 1923, it was inaugurated by the vicar general of Chur, who later became Bishop Dr. Laurentius Matthias Vinzenz. A second construction phase followed in 1927 when the restaurant was converted into a presbytery.
