Background of Luna 

The municipality of Luna which is known as Namacpacan was formerly a part of the Province of Ilocos Sur.

 When La Union was created as a new province in 1854, the town of Luna, then Namacpacan was made a part of the new province. It was during the American regime, that the name Namacpacan was changed to Luna in honor of the great Luna Brothers, whose mother Do&ntildea Laureana Novicio was from the place. 

The settlement grew and on November 25, 1690, Namacpacan was founded as a town and parish with St.Catherine of Alexandria, virgin and martyr, as patroness. Since then, the town and patronal fiesta have always been celebrated every November 25.  The original site of the town was in Darigayos,

as settlement with a small cove which served as a harbor for sea-going vessels.  In 1741, the parish was transferred to the place where it is now.The town of Luna has become a by-word especially among catholic devotees because of the several miracles that are attributed to our Lady of Namacpacan. Our lady of Namacpacan is a beautiful image of the Blessed Virgin Mary.  It was in 1871 when a galleon that came all the eay from Mexico to delivera statue of the Blessed Virgin to the Immaculate Concepcion Seminary in Vigan, Ilocos sur, stopped by Darigayos to sek cover from the stormy weather. According to traditional accounts, when the storm, is over, the galleon could not proceed to its destination because the sea became rough and unnavigable whenever the crew launched the vessel. They decided to bring the statue to Vigan by land. While making preparations, the statue was brought to the convent.  The church at that time was undergoing repairs on the damaged portions brought about by a strong earthquake.The following morning when the trip to Vigan was commence,The men could not move the statue from the place where it stood.  Fray Camilo Naves, an Augustinian priest, interpreted thisas a message that the Blessed Virgin wanted her statue to remain in the parish.  Negotiations were made with Church authorities who ordered the statue from Spain.  It was agreed that the Catholics from Namacpacan would reimburse all expenses incurred and the parishioners contributed joyously and generously to the extent of selling portions of their fields to raise the amounts. An altar at the northern portio  side of the church was constructed to house the statue of the Blessed Virgin Mary, Our Lady of Namacpacan.

 Here is the original certificate that declares that starting that day Luna is already under the province of La Union.
