Guardian Life Building, 1918.

Forced out of their previous headquarters on Cedar and Nassau Streets because of serious structural complications, the Germania Life Insurance planned a move uptown in 1909. They purchased land near Union Square and commissioned the firm of D’Oench & Yost. The resulting 20-story building, completed in 1911, was largely Renaissance Revival in style, though it featured elements of other styles, such as its eye-catching four-story mansard roof (their previous building had been a Second Empire structure with a stately mansard). The mansard, tiled in reddish-orange terra cotta, had scores of windows in various shapes and styles. And on top an electric sign broadcasted the firm's name.

Renamed the Guardian Life Insurance Company of America during the anti-German sentiments of the First Wold War, the firm had a new sign manufactured. Guardian remained in the building until 1999, when they moved back downtown. Today the building is the W New York, Union Square, a hotel.
