A cultural institution, the Numantine Museum of Soria is devoted to the sites of Tiermes, Uxama, and Numancia and collects and tells the history of the province of Soria via diverse art and archaeological displays.

The Provincial Museum and the Numantino Museum in Soria were combined to form the Numantino Museum. The former was established as a museum in 1913 as a result of the Historical and Artistic Heritage Commissions that were established in the 19th century with the Disentailment of Mendizábal in 1835. The development of the Numantia site's study, which started in the 1870s and significantly advanced between 1906 and 1923, occurred concurrently with the establishment of the Numantine Museum. The museum was finally established in 1914, and on September 18, 1919, it was officially opened in a structure constructed by Manuel Anbal Llvarez that had been initially financed by Ramón Benito Acea on land that had been donated by the Soria town council.

The Provincial Museum of Soria changed its name to the Celtiberian Museum in 1932. The Celtiberian Museum was then absorbed by the Numantine Museum in 1941, but it retained its independence until 1968, when the two centres were finally and completely combined. The two centres were then referred to as the Provincial Museum of Soria, the Museum of Soria, and finally the Numantine Museum of Soria. It had a thorough renovation in 1989, during which the exhibition space was extended to 7000 m2.

The museum organises the museum-related activities at the following locations in its province: Numancia, Tiermes (in Montejo de Tiermes), San Baudelio de Berlanga Hermitage (in Caltojar), San Juan de Duero Monastery Remains in Soria, Palaeontological Site of Ambrona, etc.

The structure has an eight quadrangular pillared entrance portico with lintels. The first structure was a one-story structure with three naves connected by two courtyards. It was expanded in the 1980s with the addition of a three-story building and a building on the courtyard's side. The Lower Palaeolithic remnants of "Elephas Antiquus" mark the beginning of the tour. Weapons and memorial stelae serve as symbols of the Bronze Age. Vases and pottery from Castros are examples of artefacts from the Iron Age. Ceramics, fibulae, pectorals, weapons, and tools from the Celtiberian era are still present at the province's sites of Tiermes, Numancia, and Uxama Argaela. Villas and necropolises are where you can find Roman-era artefacts. An examination of the province's mediaeval archaeology, which includes surviving architectural, pottery, and numismatic artefacts, concludes the visit.

For the blind and visually impaired, who can touch a variety of artefacts and copies, the tour has been modified.

It has three levels divided into six primary exhibition rooms that are arranged in two wings. The ongoing exhibit provides a chronological overview of the history of the province of Soria. The Solutrensian object known as the Villalba Plate, which was designated an asset of cultural importance with the category of moveable property in 2014, stands out in the Upper Palaeolithic, which starts with the Lower Palaeolithic and continues into the Upper Palaeolithic. There are several Neolithic artefacts to be found at the sites in the southwest of the province. Important artefacts from the Covelda deposit and the menhir stela from Villar del Alba serve as representations of the Campaniform culture and the Bronze Age.

Numerous locations show evidence of the Iron Age, but Numancia, Tiermes, and Uxama stand out. In the chambers on the higher levels of the Celtiberian Section, this era is on display.

Along with those discovered during the Roman era at Numancia, relics from the Roman occupation sites at Cuevas de Soria, Santervás del Burgo, and Quintanares de Rioseco are also on display. Additionally, Muslim Iberian Peninsula culture, which had Medinaceli as its capital during the Middle Ages, and Tiermes, Numancia, and Osma also have Visigothic influences. Following the Muslims, the Christian repopulations left significant legacies in the form of Gothic and Romanesque art.

Celtiberia

The ancient, the full, and the late periods make up the three main divisions of the Celtiberian display. Grave goods with pediment and antennae swords, fibulae, plate or spiral pectorals, and burial urns are of particular interest. The part on pottery is equally significant.

Blas Taracena Aguirre (1915–1951), Juan Zozaya (1969–1973), José Luis Argente Oliver (1974–1998), and Elas Terés Navarro have all served as the museum's directors (1999-).
