This offshoot of the Galleria Nazionale d'Arte Moderna occupies an art nouveau villa between the river and viale Flaminia. This was the studio-home of Hendrik Christian Andersen, a Norwegian-American whose artistic ambitions were monumental but whose fans were few (with the notable exception of Henry James, who, reportedly, had his eye on the man rather than his works). Andersen favoured the bombastic homoerotic style of which Mussolini was so fond. His massive bronze and plaster figures stride manfully across the studio; more interesting, perhaps, is his megalomaniacal plan for a 'world city' (1913). Temporary exhibitions in the upper rooms are rather hit-and-miss, though the top-floor café's terrace (9am-4pm Mon-Fri) is a pleasant spot on a sunny day.
