Lengwil

The municipality was created in 1998 by a merger of the Ortsgemeinde of Illighausen and the village of Oberhofen bei Kreuzlingen. During the merger, the village of Schönenbaumgarten went to the municipality of Langrickenbach. Lengwil village is first mentioned in 1159 as Leingewillare. Illighausen is first mentioned in 1176 as Illinchusen and Oberhofen bei Kreuzlingen is mentioned in 1160 as Obirhovin.
Illighausen was originally owned by the Bishop of Constance and from the Middle Ages until 1798 was part of the Bishop's bailiwick of Eggen. It became part of the parish of Münsterlingen in 1312-13 at which time, it already had a village church. With the Protestant Reformation most the village converted to the new faith and became a separate parish. However, in the 16th Century, the village became part of the Reformed parish of Altnau, and the village church became a filial church of Altnau. Since 1942, Illighausen has been part of the parish of Oberhofen. The local economy revolved around agriculture until the 19th Century when dairy farming was added. In 1900 the embroidery entered the village. However, limited road access to the village as prevented any industries from settling in Illighausen.
