on the ruins of the Roman fort. The new village of Pfyn was built northwest of the burned out old city. In 1794-95 the village built a bridge over the Thur river. They were allowed to collect tolls on the bridge until 1850. St. Bartholomew's Church, which was located within the old Roman fort, was the center of a large Early Middle Ages parish. It included the villages of Felben, Wellhausen, Hüttlingen, Mettendorf, Harenwilen and Eschikofen on the left bank of the Thur and Weiningen, Lanzenneunforn, Gündelhart, Hörhausen, Hörstetten, Dettighofen and Müllheim on the right. After the founding of Reichenau Abbey, Hüttlingen and Müllheim separated from the Pfyn parish. During the Middle Ages, parsonages were established in Felben, Gündelhart and Weiningen, all of which became independent later. In 1155 the Cathedral Chapter of Constance gained rights over the church in Pfyn, including the right to appoint the priest. They invested a canon who would serve as a vicar for Constance. The rights to appoint the church's priest went to the Canton in 1804 and to the parish itself in 1840. In 1528 the Protestant Reformation entered the village and for a short time the village converted. However, the villages belonging to the parish, such as Gündelhart and Hörstetten remained predominantly Catholic. Within 5 years, in 1533, a Catholic priest was again in Pfyn. The church was shared between the two denominations, a situation that remains today. Geography Pfyn has an area, , of .
