Now, the name. Nothing about Moscati's palace sounds Spanish, so where does lo Spagnolo come from? The answer arrives in the following century, when the family sold apartments on the lower floors — some accounts specify the first and second floors — to a buyer named Tommaso Atienza, a nobleman known by the nickname lo Spagnolo, the Spaniard. That nickname travelled with him into the building's history, and in time the palace itself became Palazzo dello Spagnolo. You may also see it written as Palazzo dello Spagnuolo, an older spelling of the same name. It is a lovely lens on this city. A palace conceived for a Neapolitan marquis carries the popular nickname of a later owner from Spain — and Naples adopted the nickname rather than the formal title. Buildings here are often known by the people who lived in them, not by the architects who drew them. There is one more layer, reported in local heritage writing: the palace is said to have housed the Istituto delle Guarattelle, a collection of local puppets and masks. Treat that as a remembered chapter rather than a fully documented exhibition history. Even so, it fits a building that has always been several things at once — noble residence, rented apartments, and, for a while, apparently a home for the city's puppets.
