The alternative tourism video starts by showing some of Rome's iconic sites, but will focus on less well-known quarters, such as the Salario-Trieste neighborhood in north Rome.

Rome's Coppedè Quarter is the focus of the segment. Its eclectic style is difficult to characterize, but the narrator talks of the liberty style, which stems from the Liberty department store in London. In English, we know this style by the French term, Art Nouveau.

The segment shows us some interiors in Coppedè's dream-inspired complex.

More dreamy interiors of the Coppedè complex and an introduction to the Keats–Shelley House in Piazza di Spagna.
