Just across the boulevard - something fancy. Rococo emerged in France in the early eighteenth century as a continuation of the Baroque business - but not as heavy and dark. The usual words used to describe it are opulence, grace, playfulness, and lightness - carefree stuff, not heroic battles or religious figures. The word Rococo is apparently a combination of the French rocaille, or shell, and the Italian barocco, or Baroque style. You do get a lot of shell-like curves and odd flowers and figures. Anyway, when the term was first used in English, sometime around 1836, it was a colloquialism meaning "old-fashioned" - and by the mid-nineteenth century it was, as everything had turned all neoclassical. Rococo hit Hollywood big-time in the late twenties, when the film industry really took off, at the tail end of the silent film era.
Actually, this is a subset of Rococo - Churrigeresque detail - floral and scrollwork cast and attached to the building - in the manner of the Spanish architect Churriguera.
