del Vista Arroyo, painting by RD Riccoboni. The Spanish Colonial Revival style del Vista Arroyo building towers over its setting and dominates the view from across the Arroyo. Originally built as a hotel during the late stages of Pasadena's great resort hotel age, the main building was constructed in two sections--the two-story north wing, in 1920, and the six-story bell tower with flanking wings, in 1930.
