Lampaul-Guimiliau (Breton: Lambaol-Gwimilio) is a commune in the Finistère department and administrative region of Brittany in north-western France. It is noted for its parish close.
The place name element lan or lam (llan in Welsh) originally signified an enclosure, particularly a sacred enclosure, and later came to mean a church. The name Lampaul therefore means church or enclosure dedicated to St Paulinus. St Pol (Paol, Paul, or Paulinus) was one of the seven founder saints of Brittany, a 6th-century Welsh missionary closely associated with the Léon diocese of Brittany, in which Lampaul-Guimiliau is situated. Parish closes are a distinctive feature of this diocese, although they are not entirely confined to it.
In the Middle Ages, the village was part of the parish of Guimiliau. This means township of Miliau, a Breton saint of the 6th or 9th century. Later, rising prosperity and economic growth brought separate status, with a separate parish church. Hence the name in full means St Pol's Church in the Settlement of St Miliau.
Parish closes are a distinctive feature of the Breton culture of the Léon region. The close is so-called because it is a church yard entirely enclosed by a wall, with a ceremonial entrance arch. The closes of the Léon diocese date from the 16th and early 17th centuries, when the area was at the peak of its prosperity, founded on the hemp industry and on Channel and Atlantic trade.
