It is not known if the name comes from Bangor Abbey in Northern Ireland, one of the most famous abbeys in Western Christianity, from where it is known that monks like Columbanus came to evangelize in Armorica in the 6th century, or from the Monastery of Bangor-Fawr, founded in Wales around 545 on the Menai Strait.

The Breton name of the commune is Bangor.

The commune of Bangor has been inhabited since prehistory as evidenced by the Pierre Sainte Anne menhir.

Bangor has been the administrative centre of the island for 10 centuries. It was the name of a priory founded by Benedictine monks who came to colonize and populate the island starting in the 7th century.

Colonization consisted of dividing the island into five parishes with Bangor occupying the middle Each parish was a small area given to residual families from the island or to colonists who were asked by the monks to come to Brittany.

In the 9th century the island was devastated by the Vikings and the priory was placed under the secular protection of the Counts of Cornouaille (in Armorican Brittany). In 1029 the Count of Cornouaille Alain Canhiart entrusted the island to the recently founded Sainte-Croix de Quimperlé Abbey. As it was directly under the authority of the Pope, Belle-Ile benefited from immunity from being under the authority of both the bishopric of Vannes and the duchy of Brittany. The administration of the island was delegated to a provost of the abbey who had temporal power (the right of low, middle, and high justice which was performed sometimes at Belle-Ile and sometimes at Quimperlé). From 1408 the right was exercised only at Quimperlé.

The Count of Cornouaille entrusted the island to the Benedictines of Redon Abbey who were able to take possession of it after long protests from the abbot of Quimperlé. The priory remained in the same spot as its predecessors (on the current location of the municipal campground of Bangor) and a fort was constructed at Le Palais which later became the capital of the island instead of Bangor.

Belle-Île was governed by monks until the 16th century when incessant attacks by pirates forced them to relinquish their fiefdom to the king, or rather to the regent Catherine de' Medici, who gave the land in vassalage to the Gondi family – then owners of the Pays de Retz. The land, however, remained under the heavy hand of the regime until the French Revolution.

The Goulphar Lighthouse on the west coast of Bangor has been active since 1836.

The semaphore of Talut was put into service in 1862.
