In the last decade the city has witnessed a good deal of growth in the quarters of Borsacchio slightly to the north, Campo a Mare along the seacoast and Voltarrosto to the west.

A major north–south rail line running along the coast passes through Roseto connecting it to the provincial capitals of Pescara and Teramo.

Later the name fell into disfavor, especially in military circles, because it sounded Austrian, a bitter enemy of Italy during World War I, and in 1927 the city was rechristened with its current name.

The name derives in part from the large numbers and varieties of rose and oleander trees which grace the byways and balconies of the city's residents.

This followed an examination of the saint's remains, which found no trace of human blood but only a vial of perfume, rings, and various assorted personal items.

A Canadian school, Centro Scuola, has organized summer language programs in Roseto and neighbouring towns for many years.
