The Palace of the Marquis of Dos Aguas (Spanish: Palacio del Marqués de Dos Aguas, Valencian: Palau del Marqués de Dosaigües) is a Rococo nobility palace, historically important in the city, is located in one of the most central locations in the city of Valencia (Spain), stately mansion that was of the Marqueses of Dos Aguas, currently owned by the Spanish State, where houses the González Martí National Museum of Ceramics and Decorative Arts.
A noble knight, Don Francisco Perellós, a descendant of the counts of Tolosa, married in the early 15th century to Joanna Perellós, only daughter of the wealthy Mosen Gines de Rabassa, the descendants of this marriage took the surname of Rabassa de Perellós. This family acquired by purchase the barony of Dosaigües in 1496, being elevated to marquisate by King Charles II of Spain in 1699.
Historians say, that the house of the Marqueses of Dos Aguas was considered in Valencia for centuries, as a paragon of nobility and opulence and that, its fortune came from the year 1500, at which time a family of merchants, the Rabassa, is enriched, first with the commercial treatment and then with the leases of the rights of the Generalitat Valenciana, i.e. the contracts of indirect contributions. The Rabassa de Perellós family continued their business with the Generalitat, while occupying high positions in the political government of Valencia and accumulated skills and important heredities through intermarriage with other important Valencian noble families.
The space in which it is located is believed that was probably originally the field intended to a Roman necropolis of the 1st and 3rd centuries, due to the findings in one of its courtyards on September 9, 1743.
