Letur

People have lived in and around Letur since the Palaeolithic. The surrounding land holds a significant group of cave shelters with prehistoric rock art from two distinct periods: Epipaleolithic art in the Levantine style, made roughly 6,500 years ago by the last hunter-gatherer communities, and Neolithic schematic art, more abstract in character, produced between around 6,500 and 3,200 years ago by early farming peoples. The first sites were discovered around 1981 by a local schoolteacher, Matías Muñoz Jiménez, at Cortijo de Sorbas I and II. Further shelters followed: Tenada de Cueva Moreno and Las Covachicas (Anna Alonso, 1985), the shelters at La Fuente del Saúco, La Casacueva, and Barranco Segovia (Manfred and Katja Bader, 1987), and Cueva Colorá and Cerro Barbatón (Alexandre Grimal Navarro, 1988–89). In 1998 UNESCO declared all these sites World Heritage, grouped under the collective designation Rock Art of the Mediterranean Basin on the Iberian Peninsula. Despite that recognition, the sites remain vulnerable through lack of adequate protection and low public awareness.

Romans, Arabs, and Christians each passed through and left their mark, but it is the Islamic period that shaped the town most visibly. The street layout, the whitewashed houses, the internal courtyards, and the drainage and irrigation systems all reflect Moorish planning. In 1983 the Spanish Ministry of Culture declared Letur a Historic-Artistic Ensemble, citing the exceptional preservation of its Islamic urban design.

In 1243 King Fernando III charged the Order of Santiago with reconquering Letur. The campaign was led by his son, the Infante Alfonso, later Alfonso X el Sabio. Under the Treaty of Alcáraz that same year, Letur was incorporated into the old Kingdom of Murcia, and subsequently placed under the authority of the neighbouring town of Socovos within the Order's jurisdiction. A description from Felipe II's Topographic Reports of 1578 portrays the town as a fresh, agreeable place full of water, greenery, and cool air. The Order of Santiago held authority over Letur until its jurisdiction was abolished in the mid-nineteenth century. On 29 October 2024 a severe DANA storm system caused a devastating flood that brought death and destruction to the municipality.

The parish church of Santa María de la Asunción is the town's most important monument. Built between the late fifteenth and early sixteenth centuries, it is largely Gothic in style, with the exception of its doorway, which is Renaissance. The Ministry of Culture declared it a protected monument on 15 December 1982.

The town hall is a Renaissance building from the sixteenth century, notable for its wide balcony and an unusual commemorative plaque that reads "Viva el Rey Amadeo I y la Constitución" — a reference to Amadeo of Savoy, King of Spain from 1871 to 1873. It may be the only public monument to that king anywhere in the country.

Two small hermitages survive in part. The Ermita de San Sebastián, on the street of the same name near the Puente de la Cruz Blanca and the entrance to the old quarter, retains a sixteenth-century Renaissance doorway. The Ermita del Alto, lower down in the old quarter, has a steep staircase recently uncovered, framing a Renaissance doorway in a style close to that of the parish church; an inscription reads "Año 1625."

Calle Albayacín is the best-preserved example of Islamic architecture in the village — a dead-end alley with an irregular layout and five small communal archways built in stone, each serving as an entrance vestibule to several dwellings.

The Mirador de La Molatica is a natural viewpoint overlooking the town's market gardens and the course of the Arroyo de Letur, which drains most of the water that rises within the municipal area.

The castle once stood in the main square. Built during the period of Arab rule, it passed to the Order of Santiago in 1242 and was the base from which Christian resettlement of the area was organised in 1454. Despite being covered by national heritage protection legislation, the castle remains were demolished in the mid-twentieth century and replaced with residential buildings.

Other heritage features include the Arco de Las Moreras, the Cuesta de Los Molinos, the Puente Medieval, the Charco de Las Canales, the Charco Pataco in the Huerta de Los Cantalares, and a waterfall on the Arroyo de Letur. The hamlet of La Abejuela has its own small popular-style hermitage, the Ermita de San Bartolomé, built around the eighteenth century.
