Beautiful half-timbered houses. Few public benches. Those in front of the church and in the adjacent playground are not sheltered from the wind. If you have a picnic area to recommend, go for it, thank you.

Next to the restaurant you also have a camping. The camping is quite rudimentary, but its most important asset is the restaurant. Unfortunately it is only open during restaurant hours. You eat well here, but beware, the restaurant appears to be very popular locally. The restaurant runs on its local guests and not on the camping guests. Both are owned by the same owner.

Oltingue is a quiet village in the Sundgau with a late-classical village ensemble around the church of Saint-Martin (1827–1831), the rectory and the former school. The Callinet organ (1843), the double staircase of the rectory and the facade details are striking. There are several historic houses in the village, including half-timbered houses from 1695 and a farm from the 16th century. To the east lies the chapel of Saint-Brice, a former place of pilgrimage with a baroque altar and an outdoor pulpit.

This former mother church of Oltingue and three disappeared villages dates from the 13th and 14th centuries. The location is idyllic: surrounded by fields, an old cemetery and often with storks on the roof in the spring. Inside you will discover surprisingly well (?) preserved wall paintings, including a rare representation of the sacrifice of Melchisedech and a Last Supper from 1741. In the choir you will also find a wall tabernacle and a niche for liturgical objects, silent witnesses of medieval rituals. The Gothic arched windows and the neo-Gothic vault are reminders of later restorations, while archaeological excavations in 1989 revealed traces of older sanctuaries and tombs from the early Middle Ages. simple but full of character.

Raedersdorf is located in the southernmost part of Alsace, in the hilly landscape of the Sundgau, close to the Swiss border. The village is surrounded by forests, springs and hiking trails leading to heritage sites such as the Église Saint-Étienne with its baroque interior and Callinet organ, and the Mariabrunn chapel in the forest. Its location between French-speaking and German-speaking Switzerland makes Raedersdorf a place where cultures come together.

The church of Raedersdorf was built in its present form between 1807 and 1811, on the foundations of an older church, the tower of which has been partly preserved. The interior was richly decorated in 1811 by sculptor Joseph Antoine Feuerstein, with a harmonious baroque ensemble. The organ was also built in the same year by Jean Frantz. The church was finally consecrated in 1851. It is located in the centre of the village, close to the town hall, and is a silent witness to religious art and village history in the south of Alsace.
