Tréguier (Trecorum), which dates from the sixth century, grew up round a monastery founded by Saint Tudwal (died c. 564). In the 9th century it became the seat of a bishopric, suppressed on July 12, 1790 (decree of November 14, 1789). Pop. (1906), 2605.
Inhabitants of Tréguier are called trécorrois in French.
In 2008, 11.78% of primary school children attended bilingual schools.
The cathedral, remarkable in having three towers over the transept, one of which is surmounted by a fine spire, dates from the 14th and 15th centuries. It contains the sumptuous modern mausoleum of Ivo of Kermartin (St Yves; d. 1303), a canon of the cathedral and patron saint of lawyers. The building of the cathedral was largely due to him. The Pardon of Saint Ivo, a religious festival, attracts an international audience drawn from the legal profession. To the south of the church there is a cloister (1468) with graceful arcades.
Near the cathedral there is a statue of Ernest Renan, a native of the town. As he was a prominent skeptic, author of the "pagan" Prayer on the Acropolis, the 1903 unveiling of Renan's statue, which also included a depiction of the goddess Athena, led to widespread protests from the Catholic Church. The town also houses the Renan birthplace museum. A notable war memorial, the Pleureuse de Tréguier, was designed by Francis Renaud. A commemorative memorial to Anatole Le Braz by Armel Beaufils is in the jardin du poète.
The port and harbour are picturesque, containing many pretty waterfront restaurants and crêperies. There are dramatic views of the quayside.
Saw-milling, boat-building and flaxstripping are carried on, together with trade in cereals, cloth, potatoes, etc. The port carries on fishing and a coasting and small foreign trade.
The Pardon of Saint Yves is a major event. As Yves is patron saint of the legal profession, it attracts Catholic lawyers and judges from all over the world.
