"Casa Zapata" is a wonderful and complex residence erected by the ancient and noble Aragonese family of Zapata from the end of the sixteenth century. The members of this family arrived in Sardinia in 1323 Following the Infante Alfonso who was preparing to conquer the island, they settled, then, Cagliari (one of City Royals) It is in the 1541 They bought the Barony of Las Plassas, Barumini e Villanovafranca, becoming lords and barons then, and coming to administer until the suppression of the feudal regime. Among the various buildings that make up the residence are distinguished: a beautiful building, with elegant adjoining garden, built between the late sixteenth and early seventeenth century to become Baron's Office and the feudal lord, and two masonry bodies of agricultural relevance, accomplished since the early 1900, used as warehouses, barns and farm house open onto a large courtyard that allowed the free movement of men, goods and animals. First "Casa Zapata" is located the Parish of Our Lady Immaculate, whose construction was probably commissioned by the noble Aragonese family. Today the Spanish residence is home to the Museums of the so-called "Casa Zapata" ?? organized into three sections. The Archaeological Section, entitled on 11 December 2014 all'esimio Professor Giovanni Lilliu, It has been set up inside the oldest part of the residence, a beautiful building built according to the classical model imposed by Philip II with form and style imitating the palace of the Zapata family in Cagliari. It deals with, then, a beautiful seventeenth-century palace, during the last century, It was identified as an ideal location for safekeeping and enhancement of important finds in the archaeological Su Nuraxi. To this end, after the death of the last Baroness, Donna Concetta Ingarao Zapata, which took place in the 80s and a period of disrepair, the City of Barumini it bought the property in 1987. Circa 3 years later, in 1990, unaware of the treasure "Casa Zapata" ?? kept inside, They began work towards the realization of the project musealization. Works which were soon interrupted due to the discovery of the remains of an impressive complex nuraghe under the building structures. Since then you have followed numerous excavations, ongoing, and it has carried on a museum project that sought to protect and not to distort the construction of the building and at the same time to make available the vision of the nuragic top, via a system of suspended walkways and glass floors. It, then, extraordinary enter the interior of a palace and then unexpectedly find in front of a dolmen of this size. It was Prof.. John Green writing, even before the start of archaeological excavations, that near "the palace 'and the marquis, the ancients established a dolmen and a small group of huts around "??. An archeology that same renamed Su Nuraxi 'and Church (The dolmen of the church ??), because of its proximity to the parish church and that populations nuragiche built on this site (ie on a shelf marl rock) since it was level, high enough to dominate the surrounding area and was not far from water sources. One of the possible functions of the nuraghi had, indeed, be the military. "Su Nuraxi 'and Church" is a complex nuraghe trefoil, It consists of a central tower, called "tower" ??, around which are arranged three radiused perimeter towers by rectilinear curtain walls. it presents, Moreover, the particularity of being equipped with 2 courtyards, one inside the trilobate bastion, with well, and an external connected to the first by means of an architrave entrance place in the curtain wall of Southeast. Archaeological excavations made since 2005 right in the outdoor courtyard made it possible to highlight the original flooring of the structure, It consists of paving which we know to be dating back to the Bronze Age through to the materials found therein. Excavations carried out in Casa Zapata and on the southern side put, Moreover, light in the presence of a double rampart and a village settlement structure. Being the ongoing excavations can only speculate the joint chronological stages of the monument: at a first time ranks the construction of the keep; to a second stage that of the South and East towers and of the connecting curtain; finally, a third phase that of the perimeter West tower, precisely because it was built in basalt and, then, with an obvious change of constructive material. The archaeological deposit of Su Nuraxi 'and Cresia returns a horizon and a cultural stratification that goes from the period nuragico (from the Bronze Age 1300 a.C., and the Bronze Final 1100-800 sec. a.C.) until the Roman period (Late Republican and late imperial) and altomedieval; exceeded the Ages Old Su Nuraxi 'and using a recorded attendance age Judicial, until you get to the Zapata building construction. The towers, which originally had to be much higher, they are today svettate, ie missing the summit parts, had a frustoconical shape and at their inner circular presented superposed chambers with protruding walls and cover tholos (a false dome). Currently in Casa Zapata they are visible the tower and the east tower, while the South and West tower, double rampart and the village grow outside the structure. For the construction of nuragh blocks they were employed polygonal, locally marl, large, arranged according to horizontal rows; sporadically also it appeared with the presence of basalt, a harder volcanic stone, coming from the slopes of the Giara and used for the construction of Su Nuraxi ?? Barumini. The archaeological section, in addition to Nauraghic, It houses a prestigious collection of artifacts (over 180 pieces) found in the archaeological "Su Nuraxi" ?? following the excavations conducted by prof. Giovanni Lilliu during the '50s and restored by technicians of the local laboratory of archaeological restoration. Products of the material culture and especially ceramic objects that are index fossil and represent valuable timelines. The section-Historical Archives was set up inside one of the buildings making up the agricultural relevance and it is on the inside that you can admire some of the most important documents in the Zapata family and the community of Barumini. In the cases they are kept the precious documents in the original, once thought disappeared and recently found and purchased by the Municipality of Barumini, while the panels are portraits of some of the most important documents that are part of the private collection of the pro-grandson of the last Baroness Donna Concetta Ingarao Zapata. It is a collection of over 10.000 documents, that Dr.. Andrea Lorenzo Ingarao Zapata Las Plassas has kindly made available to the public in digital format and then accessed through computers used in the media room in the historic part. The Ethnographic section, always set inside of buildings used as agricultural relevance, It consists of a small room host some of the most common objects of the last century belonged to the inhabitants of Barumini and neighboring countries; with annexed the "Regional Museum of Launeddas" ??, small space dedicated to the ancient Sardinian musical instrument, set up thanks to the contribution of the master Luigi Lai ??.
