The Shelleys spent the winter of 1818-1819 in Naples, and it was a wretched three months for everyone. 

Mary was gloomy and tired, Claire was ill, and Shelley depressed and in poor health.  Part of the problem might have been the arrival of Shelley's mysterious "Neapolitan charge":  Elena Adelaide Shelley, born in the Shelleys' comfortable lodgings at 250 Riveria di Chiaia on 17 December.  The truth of the matter has never come out:  was she Shelley's daughter by Elise; who had been pregnant at the time; or by Claire, as a later rumor had it; or had Shelley kindly (but incomprehensibly) offered his name to the child of Elise and the servant Paolo?   She was eventually placed in the care of a foster family and died a year later.

The 250 apartments no longer stand—they have been replaced by (alas) one of the very few modern buildings in the area. One can guess at what they might have looked like, however, by examining at the building next door--typical of the architecture of the area. The rooms faced the lovely Royal Gardens, and afforded magnificent views of the Bay of Naples and Capri.
