Autobahnkirche Horgau, Catholic highway church near Adelsried, Germany.

The Autobahnkirche Maria, Schutz der Reisenden stands beside the A8 at the Adelsried junction. Raimund von Doblhoff built it from 1956 as a concrete frame on a 17 by 14 metre rectangular plan, the scale of a Swabian village church. Front and rear walls with the choir tower are almost fully glazed, and a two-part sliding glass door opens under a wide canopy. Inside, about 300 people fit; a Gothic crucifix with a three-metre corpus, mid-14th century and under monument protection, hangs above the altar.

The Augsburg paper manufacturer Georg Haindl donated the church in memory of two family members and on the birth of his son. Raimund von Doblhoff, a friend of Haindl, made the first studies in 1955 and built it from 1956 as Germany's first motorway church. The Augsburg bishop Josef Freundorfer consecrated it on 12 October 1958 and handed it to the Dominican monastery Heilig Kreuz.

The name itself refers to protection for travelers, reflecting a German tradition of creating spiritual spaces at motorway stops. Visitors find a place designed specifically for drivers to pause during their journey.

The church is accessible daily and offers a quiet place to pause during a motorway drive. Plan about 15 to 20 minutes to visit the church and use the facilities.

The church was funded by Augsburg paper manufacturer Georg Haindl in memory of two family members and on the birth of his son. Its name refers to the Flight into Egypt (Mt 2:13-15). From 2006 to 2020 it was looked after by Father Wolfram Hoyer, who died in 2020 aged 51 after being struck by a trailer while placing a warning triangle on the A8 near Sulzemoos.
