Palazzo Turinetti di Pertengo is a noble building of seventeenth-century origins gradually transformed. Commissioned by the Marquis Giorgio Turinetti di Priero, banker of the Duchy of Savoy, the palace overlooks Piazza San Carlo with its long portico to qualify, in concert with the other buildings, the harmonious unitary design of the city lounge. Following the damages of the Second World War and the subsequent architectural competition to make it a seat of high representation in which, among others, the architect Carlo Mollino participates, in the 1960s "modern" buildings were built in the internal courtyard, designed by Arturo Midana and Mario Dezzutti, included in the new Gallerie d'Italia.

The construction story of Palazzo Turinetti is closely linked to the great project which, between the sixteenth and seventeenth centuries, endowed Turin, which officially became the capital city of the Savoy State, with a new urban and architectural configuration. The current Piazza San Carlo was born during the seventeenth century as Piazza Reale, intended for large noble residences: a complex project, led by the ruling family, through a land policy based on the donation of land to the nobles, on condition that they build their palace there quickly and at their expense according to the pre-established architectural design. Today the Palace contains fixed furnishings and furniture of great value, also the result of acquisitions and transfers from other city residences, such as Palazzo Solaro della Chiesa then Mazzonis di Pralafera, including boiserie, stucco, mirrors, precious carvings, French-made tapestries and paintings from the seventeenth to the twentieth century by artists such as France, Cignaroli, Rapous, De Mura.
