New York City Mayor Bill de Blasio and his family, back in the United States following a vacation in Italy, have moved in to Gracie Mansion, his office confirmed.

That’s pretty much the entirety of the news in this post, but if you are in the market for a little more about the history of Gracie Mansion, here you go: This marks the first time the mansion has had a mayoral resident since 2001, when the house’s six-decade run as the literal mayoral abode came to a close. Gracie Mansion used to be a museum and, before that, was home to public bathrooms and an ice cream parlor for Carl Schurz Park. (There’s much, much more about the history of the mansion and the grounds in this brochure, in case you enjoy reading brochures.)

Fiorello La Guardia, the 99th mayor of New York City, was the first mayor to live in the mansion, starting in 1942. The next eight mayors all moved in, though De Blasio’s predecessor, Michael R. Bloomberg, chose to never spend a night there. Bloomberg, who spent millions on a renovation of Gracie Mansion, insisted that no mayor should live there because it would “take one of the great houses in this city away from the public,” he said in 2012. (Former mayor Ed Koch disagreed, comparing that to asking a president not to live in the White House. Similarly, former mayor David Dinkins urged de Blasio to live in the mansion.)

The last time the mayoral home was home to a mayor was in 2001. Rudolph Giuliani moved out “to escape the tension in his failed marriage,” to quote the New York Times (that same article referred to Judith Nathan — Giuliani’s then-girlfriend, now-wife — as his “friend,” as the Times did when a judge barred her from the mansion).

De Blasio has called the decision to leave Brooklyn for Manhattan temporary, pointing to unspecified “logistical and security concerns” as the reasons for departing Park Slope. Upon returning from a recent trip to Italy on Sunday afternoon, the de Blasio family planned to spend their first night in the mansion.
