The Álzaga Unzué palace speaks of an Argentina of the beginning of the last century, with a society of contrasts between the arrival of poor Europe and the Creole agro-export aristocracy that looked at Europe and dreamed of a new Paris on the banks of the Río de la Plata.

It has the typical structure of a hotel particulier of the Belle Époque: a large mansion designed where a single family with four floors of well-defined functions would live.

He built it with a French neoclassical style that is still inspiring and unique today.
