Katholische Kirche St. Gallus, Catholic church in Lichtensteig, Switzerland.

St. Gallus Catholic Church is a concrete building designed by architect Walter M. Förderer and constructed between 1968 and 1970 on a hill above the old town of Lichtensteig. It replaced a neo-Gothic church from 1866–1868 that had become structurally unsound. The church was consecrated by Bishop Josephus Hasler on 18 October 1970.

The present St. Gallus church was built in 1968–1970 to plans by architect Walter M. Förderer, after the parish decided in 1965 to replace its previous church. That earlier church, rebuilt in Neo-Gothic style in 1866–1868, had been used jointly by Catholics and Protestants since 1531. The Catholic community took over the old building and paid out the Protestant parish, which then built its own church. Bishop Josephus Hasler consecrated the new church on 18 October 1970.

The parish was founded on 17 October 1435 after Lichtensteig's residents and Count Friedrich VII of Toggenburg raised money, with the mother parish of Wattwil compensated and the abbot of St. Gallen's appointment right settled. From 1531 to 1967 the town church was used jointly by Catholics and Reformed. The relics of the Roman martyr Marianus, translated in 1657, rest on the right side of the chancel.

The church stands on a hill above the old town of Lichtensteig, reached on foot via the lanes climbing from the centre. The building is normally open around services; check the parish's current times before making the climb.

The church was designed by architect Walter M. Förderer and built between 1968 and 1970; its competition entry carried the title "Campagne" and won first prize on 12 May 1966 ahead of projects by Justus Dahinden and Ernest Brantschen. The relics of the Roman martyr Marianus rest on the right side of the chancel, brought to Lichtensteig in 1657 in a procession with a Baroque pageant.
