Porrentruy

Porrentruy (French: [pɔʁɑ̃tʁɥi]; Franc-Comtois: Poérreintru [pweʁɛ̃tʁy]; German: Pruntrut) is a Swiss municipality in the canton of Jura. It is the seat of the district of Porrentruy. In 2018 the municipality had a population of 6,675.

Porrentruy is home to National League ice hockey team HC Ajoie.

The first trace of human presence in Porrentruy is a Mesolithic tool that was found in the backyard of the Hôtel-Dieu. Scattered, individual objects have also been found from the Neolithic, the late Bronze Age and the Iron Age. The first known settlement in what became Porrentruy goes back to the Roman era. In 1983, the ruins of a Gallo-Roman temple were discovered in the cemetery on the north of town, and Roman coins were found there. Near the town, a kilometre long (0.6 mile) section of the Augst-Epomanduodurum (now Mandeure) Roman road was discovered.

In the backyard of the Hôtel-Dieu the charred remains of a building from the 10th or 11th century were discovered. However, the first historical mention of the name occurs in 1136 as Purrentru. The name presumably comes from the Latin pons Ragentrudis (Ragentrud bridge). Ragentrud was the wife of the Frankish King Dagobert I. The German form of the name, Pruntrut may have a separate etymology from Bruntrutum, which means an abundant spring.

The first settlement was established in 1140 in the vicinity of the Church of Saint-Germain, which was built in the Early Middle Ages. The Counts of Pfirt, who owned the region around Porrentruy, built a castle on a defensible hill and made it the capital of the Ajoie territory. A settlement (now known as the Faubourg de France) was founded at the foot of the castle, with another south on the opposite hill. The city wall was probably built before 1283 and surrounded the two settlements, but not the parish church of Saint-Germain.

In 1236 the Counts of Pfirt pledged the town to the Counts of Montbéliard, however, they retained their rights to the Ajoie until 1281 when they sold the territory to the Bishop of Basel. The Counts of Montbéliard refused to hand over Porrentruy, which led Bishop Henry of Isny to request support from King Rudolph I of Habsburg. After six weeks under siege, the Count relented and handed it over to the Bishop. On 20 April 1283, the king asked the Bishop of Basel to grant Porrentruy a town charter and make it a free Imperial city. While the Counts of Montbéliard retained some power in the town, their influence waned during the 13th century.

Financial difficulties forced the Bishop to sell the Ajoie (including Porrentruy) back to the lords of Montbéliard in 1386. But in 1461, the town once again became subject to the episcopal see. Because of the Reformation in Basel, the Bishopric moved its official headquarters to Porrentruy in 1527. Under Bishop Jakob Christoph Blarer von Wartensee, who reigned from 1575 to 1608, the town reached the apogee of its importance. In his time, many architectural projects, including expansion of the castle and the building of a Jesuit college, were undertaken. This period of prosperity ended in 1618 with the outbreak of the Thirty Years' War. Porrentruy was repeatedly occupied, besieged, and plundered.

The first parish church of Saint-Germain was replaced in the 13th century by a new building, which underwent several renovations. The Church of Saint-Pierre was completed in 1349 and became the parish church in 1475. The cathedral chapter was established in 1377. Several religious orders were active in the city, including the Jesuits who built their college in 1591. In addition to the Jesuits other orders included the Ursulines (1619), the Sisters of the Annonciade (permanently established in 1646) and the Capuchins (1663).
