Thecommune is in theFinistèredepartment in northwestern France. Situated on the peninsula ofPenmarc'h in the far southwestern part ofLower Brittany, it preserves elements of old Breton culture, and the Breton language is still in use.
The name means "place or hermitage of St Tudy". There is controversy concerning the identity of the saint: bothTudy of Landevennec andTudwal have been suggested. The eleventh-century church is dedicated to St Tudy.
The port grew because of its sheltered position protected from the prevailing southwest winds. The fishing port is important (2004-6: around 7000 tonnes per annum landed), and specializes inlangoustines, called "demoiselles de Loctudy". The four ports of the Penmarc'h peninsula (Guilvinec,Saint Guénolé Penmarc'h, Loctudy andLesconil) land 40 000 tonnes per year and constitute the largest fishery in France. Amarina was constructed in 1991 and had (2006) 661 moorings.
