Arqui from the beginning has as its dominant element in their destiny the water: that smoking, of course, rich in therapeutic properties, which flows into the city center and beyond the Bormida, at the foot of the Witch Mountain. Its ancient name, "Aquae Statiellae", alludes to the abundance of thermal springs, the same remember during their primitive splendor by Pliny the Elder and Strabo. More dell'etimo and literature, however, the past of Acqui terme monumental property rises in the residual water supply facilities of the century. d.C .: those arches and stretches of pipe that once drew water from the Erro stream to feed, in addition to public and private fountains, especially the pools of the spa complex. In this regard, it has recently been restored and made open to a wide pool terraced steps belonging to a large Roman structure next to the Hotel "Nuove Terme"; while another major seaside hotel "", found in the last century in the area of ??the neoclassical temple of Boiling Square, is visible at the site of the mosaic floor which reported the names of the buyers. It surely was referring to this spa complex the Lombard Paul the Deacon when the end of the eighth century, in his "Historia," Acqui remembered as "... ubi sunt aquae calidae ...", the same way of Cremona Liutprand bishop in twentieth century, even in the darkest moments of Saracen raids, identified the city with the Boiling spa area. With the momentous changes following the year one thousand and training of Acqui City it will also for the thermal properties renovation: their rebirth in a historic setting totally changed. Dates back to the end of Millecento the extension, by the municipality, the walls around the "Boiling" and the excavation of the large swimming pool with steps, or public bath which for the centuries, the look and the same name to the square. At the end of the Middle Ages, then, around 1480, due to construction work promoted by Cardinal Theodore, brother of William VIII Marquis of Monferrato, the spa facilities beyond Bormida development that will begin during the sixteenth century, will lead to completely supplant the towns. so you come to the seventeenth century, a time when only a few bathrooms in the city will remain in operation, while the plants from beyond Bormida, ingranditisi gradually until reaching one hundred and more dressing rooms, in 1687, after a disastrous landslide, will be completely rebuilt at the expense the Duke of Mantua in the forms that despite the changes made over the centuries still form the backbone of the Hotel "Terme" Ancient. The "Royal Factory project", by the architect Giovanni Battista Scapitta Casale, with its spatial organization quadrilateral porch circumscribing the open-air pool, spa architecture will have a powerfully innovative character not only Italian, but also European, the which only in the first half of the eighteenth century, first of all, in Bath, Vichy and Plombieres present as organic and functional solutions. With the progress of time the above "factory" and the area will be subject to different interventions. The major will happen in 1789, when the architect Giovanni Battista Ferroggio will lead to running the old project to separate the plants and the military housing with the construction of a new factory adjacent to the scapittiana. The eighteenth-century perspective to make the health resort place of complete mental and physical regeneration and not only care, already implicit in the separation of the military from civilian facilities, will continue in 1826 / '27 at the hands of King Carlo Felice with the erection of a first "home pel hospitalization de 'poor' and, then, with the addition of two wings Directed to the factory and the complete redefinition of the gardens inside and outside it. The separation of the baths "poor" by the "Antique" will find a final settlement and extremely innovative with the erection, in 1847, of the "Carlo Alberto" the engineer Lorenzo Gianone. The same Carlo Alberto, then, will be the promoter of the bridge over the Bormida ended in 1850, a fundamental connection with the city, which in its late nineteenth-century urban development will grow right along the road (Corso Bagni) created by the erection of the bridge. At the height of this track, in fact, just outside the old walls, where it is now Piazza Italy, in the decades 1870 / '80 will arise and take shape slowly the Hotel "Nuove Terme" and its facilities; the other d'Acqui spa center, from centuries neglected despite the great Napoleonic project of use for medicinal purposes in the San Francesco, so will return invigorated to shine and to support, as it still is, the spa area d ' Oltrebormida. Foreword to this rebirth will be in 1868 the passage of the United Terme to the City of Acqui, represented by the figure of his greatest politician, the future Senator Giuseppe Saracco. After that, in 1879 it will open a first treatment plant, completed in 1881 with regard to the hotel part. The design of this first site, including the front facing the current Piazza Italy, then radically changed in 1930, and the Corso Bagni, will be signed by Malvani engineers, De Bernardi, Ferrari and Ceruti. A second site directed by engineer Mario Vicari lead in 1889 to the completion of the interventions with the erection of an organic and elegant new Department of jutting care to the inner garden of the "Nuove Terme". With the advent of the thirties of the last century, at the instigation of Ambrose Michetti dealer spa, Terme di Acqui know a period of significant structural growth. In fact, between the end of 1929 and 1930 it will be renovated the front towards the square Hotel "Nuove Terme" and rebuild the Treatment department of the same building, department that is currently in use. On the same lap of years in the area "Bagni" will be erected the Kursaal; in 1931 in a little more than two months it will build the new Treatment department "Queen", still in use; in 1932 the large outdoor pool, originally equipped with thermal water; in 1934 it will intervene in the Hotel "Il Molino" to erect a large new "Hall"; Finally, in 1938 it will be built alongside the Treatment department the Hotel "Regina". At the height of this important period, in 1939, the Acqui Terme will again demanializzate and only recently, in 1998, will return to being administrative relevance of the City of Acqui and especially of the Piedmont Region, which will start a general work of renewal of Company's real estate assets which, although still in progress, conducted in a few years to complete renovation and extension of the Hotel "Nuove Terme", the birth of a grand hall of the Department "Queen" dedicated to fitness and spa elevation a department of the latter plan, resulting in the creation of new and elegant use of space for medical treatment and visits.
