Together with the folkloric richness of its "trovos" (improvised poetry), "cantes" (folk signings)and the famous Festival Internacional del Cante de Las Minas (International Festival of Folk Singings in Las Minas), La Unión has a vocation to its Holy Week, whose tradition is as ancient as the own city. It is necessary to take into account that the Cofradía del Nazareno (Brotherhood of the Nazarene Christ) managed to received the denominations of Real and distinguished granted by the Spanish Queen Isabel II in 1862. In the Unión, singular and passionate processions are offered; those processions are closer every day of finding their own identity, in which the national competition of "saetas" (sacred songs) of each Maundy Thursday has a key role. The Saeta is born in La Unión when the "jondura flamenca" (flamenco depth) and the Holy Week concur with the full moon of April. Those "cantes" are quite linked to this period of the year. Although it is unknown when the first "saetas" appeared in this land, it is such an unforgettable experience hearing them during the night on Maundy Thursday, followed by a religious silence.
It is also worth seeing the Santo Entierro de Cristo (Holy Burial of Christ), during the sunset of Good Friday, a procession which starts with the beautiful statue known as "convocatoria" (announcement) and finishes with the Soledad (Virgin of Solitude), a statue which was called "lirio de luto" (mourning iris) by a poet, and which shows off a typical "trono de piña" (throne with the form of a pineapple) enlightened by three hundred lampshades.
