Katharina von Siena Fällanden, Modern Catholic church in Fällanden, Switzerland.

Katharina von Siena Fällanden is the Roman Catholic parish church of Fällanden, built in concrete in a modern style and consecrated in 1992. It is the only church in the Diocese of Chur dedicated to the mystic and Doctor of the Church Catherine of Siena (1347–1380). The parish vicariate also serves Benglen and Pfaffhausen.

Archaeological excavations revealed evidence of an early field chapel around 810, which received its first written mention in 1271. The building standing today was constructed in the postwar period as a modern successor to this long local religious tradition.

The church is the only one in the Diocese of Chur dedicated to Catherine of Siena, the mystic and Doctor of the Church born in Siena in 1347 and dead in Rome in 1380. The dedication was chosen by the parish community itself, which picked the patron from four candidates put forward by the parish council.

The church is located at Sunnetalstrasse 48 in Fällanden and is open during daylight hours for visitors and worshippers. It serves the local communities and neighboring villages including Benglen and Pfaffhausen.

The choice of patron saint was determined through a popular vote, with the parish council submitting four candidates for the community to select. This democratic process made it a place consciously shaped by local choice.
