Pfyn is a municipality in Frauenfeld District in the canton of Thurgau in Switzerland.

Pfyn gives its name to the ancient Pfyn culture, one of several Neolithic cultures in Switzerland which centered on intensive pig farming and trading, dating from c. 3900 BC to c. 3500 BC.

Pfyn was also the site of a Roman era frontier outpost, named Ad Fines (Latin: meaning "at the borders")

History

Pre-Roman Pfyn The oldest traces of a settlement are about west of Pfyn in the former peat bog of Breitenloo. Located in a depression carved by a lateral moraine of the Thur glacier, it dates from the Neolithic era (4300 BC). The settlement site was discovered during peat cutting in the late 19th century, but subsequently forgotten. During the war years 1940-41 an attempt to drain the bog to increase arable production land, led to its rediscovery. drainage work on arable production was raised again. In the autumn of 1944, an area of approximately was excavated by interned Polish soldiers led by Charles Keller-Tarnuzzer. Due to the topographical conditions, and an exploratory drilling project in 2002, it appears that about 60% of the settlement area has been excavated.

Keller-Tarnuzzer noted that there was the close relationship of the ceramics with the Michelsberg culture of southern Germany, and believed that the Pfyn finds were a Michelsberg settlement. Around 1960 research determined that the Pfyn ceramics were represented an autonomous culture that was related to the Michelsberg culture. Since that time, the Pfyn-Breitenloo site has been regarded as the center of the Pfyn culture. Further explorations in 2002 and 2004 led to a somewhat more nuanced picture of the settlement. This enabled the site to be dated via dendrochronology. The timbers that were used were cut in 3706-3704 BC. and confirm a single development phase. Another Neolithic settlement must have existed some northwest of Breitenloo. However, the few ceramics discovered at that site are also part of the Pfyn culture. That settlement has never been systematically studied and it is believed that the industrial peat extraction during the second World War may have largely destroyed it.

Because of Pfyn's importance as the home of the Pfyn culture and also as the site of a Roman era fort, other archeological discoveries have been largely ignored. For example, a number of Bronze Age artifacts and scattered grave sites were known to exist, but haven't been studied until recently. Recent excavations have discovered a Bronze Age village and traces of a previously unknown Iron Age settlement.

Roman settlement The identification of Ad Fines, which is first mentioned in 280 AD, with Pfyn is undisputed. It is also clear that the place-name refers to the provincial border between the provinces of Raetia, Gallia Belgica and Germania Superior. The course of the Roman road from Oberwinterthur (Vitudurum) to Frauenfeld through Pfyn and on to Arbon (Arbor Felix) is well known. What remains uncertain, however, is the course of a road to Eschenz (Tasgetium), as well the road towards Gotthard Pass via Irgenhausen Castrum, Centum Prata (Kempraten), Obersee–Linth–Walensee. The traces of an imperial settlement almost entirely missing. In addition to references to a farm in the records, some Roman items and parts of a large stone building have been found.

The situation is different for the late-Roman era, where the location of the hill fort outside the town is well known. The hill is now eroded by the Thur and Mühlebach rivers, and has nearly vanished in the south and east. Of the wall, only parts of the north and west still survive. Within the fort many coins and other objects were found that indicate that the fort was occupied Roman soldiers, including mounted troops, from the later 3rd century until the beginning of the 5th century. During this time, the fort connected the rear lines of defense along the Rhine between Arbon and Oberwinterthur (Limes). While nothing is known about the end of the fort, the age of nearby St. Bartholomew's Church indicates that some settlement remained after the fort was abandoned.

Pfyn in the middle ages Within the church, a number of medieval graves, have been discovered. The medieval landlord was the Bishop of Constance. In 1414 and 1502 the village received some limited self-government from the local provost. Before 1488 the bailiwick was under the authority of the Ministerialis (unfree knights in the service of a feudal overlord) family of Klingenberg. It was sold in 1488 to Jacob Mötteli. In 1560 the village was acquired by Peter of Gundelfingen, then in 1567 by Count Otto of Eberstein. In 1584 it was bought by Wolf Wambold of Umstadt, and finally in 1614 by the city of Zürich. Under Zurich a Vogt was appointed, who ruled until 1798.

In 1476 a fire destroyed the old town, which had been built 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.
