It is located in the historic center of the city, opposite the monumental Basilica of Santa María. It is an impressive newly built structure that occupies an entire block and incorporates the austere volume of the Casa de La Asegurada, the oldest civil building in the city, constructed in 1685 as a wheat warehouse and a notable example of Valencian Baroque architecture.

The MACA is one of the most important cultural institutions in the city and is owned by the Alicante City Council, although the rehabilitation project and construction of the new building were financed by the Generalitat Valenciana. Designed by the Sancho-Madridejos Architecture Studio, it has a total surface area of 4,680 m² distributed across four above‑ground floors and two basement levels. It includes a temporary exhibition gallery and four galleries dedicated to the display of the permanent collections, as well as spaces for the library, education, the assembly hall, collections storage, storage, workshops, security, administration, etc….These expansive, light-filled spaces showcase the museum’s diverse and rich contemporary art collections, guided by a rigorous museographic program where conservation and education are the top priorities.

The Casa de la Asegurada is the oldest surviving civil building in Alicante. Dating back to 1685, it has been city property ever since. Located on Villavieja Street, at the corner of Instituto Street and overlooking the monumental Plaza de Santa María, the building retains an original built area of 706 m². It stands as one of the most sober examples of Valencian Baroque architecture, reflecting its original purpose: a municipal granary or wheat warehouse (pósito de trigo). The ground floor housed the flour stores, the first floor contained offices, and the second floor served as the granary itself.

The building is arranged over three floors, each divided into three bays parallel to the main façade, corresponding to three arcades with semicircular arches. The arches rest on rectangular pillars with smooth shafts, a pronounced base, and an impost. The façade also openings three openings per floor, with the upper floors opening onto balconies. The overall composition is completely symmetrical, and it is the San Julián stone that gives La Asegurada the splendid presence that characterizes it.

The general structure, with its very simple lines, remained essentially unchanged despite the various uses it had throughout its history: it served as the seat of the Municipal Council from 1691, after the City Hall was destroyed by French bombardments, until the completion of the new Consistory building. At some point, Artillery Depot and a prison. In 1845 it became a Secondary Education Institute, and in 1893 it was converted into the Professional School of Commerce. From the 50s of that century, onward it remained without a defined use until 1966, when it was proposed as the new home of the Municipal Archive. Renovation works continued until 1976. It was then that Eusebio Sempere intervened and considered La Casa de La Asegurada the best location for the exhibition of the 20th Century Art Collection that the artist himself would donate to the city. The Museum of La Asegurada thus opened its doors on November 5, 1977, becoming one of the pioneer Contemporary Art Museums in Spain.

More than 30 years later, the Casa de la Asegurada is now part of the new MACA. The architectural project seamlessly integrates the historic building into its modern structure.
