The class was a group of eight
torpedo cruisers built for the Italian (Royal Navy) in the 1880s and 1890s. The class comprised , , , , , , , and . Based on the earlier cruiser , the class represented a temporary embrace of the , which emphasized the use of cheap torpedo-armed vessels as a means to defeat the much more expensive

Design
The design for the class was prepared by Engineering Inspector
Carlo Vigna, and was based on the earlier
torpedo cruiser , the first modern vessel of the type built by Italy. The development of torpedo cruisers in Italy in the mid-1880s represented a shift away from the emphasis on large

The ships were protected by a curved armored
deck that was up to thick; the deck was flat over the longitudinal center and sloped down at the sides to connect to the outer hull plating. Their forward conning towers were armored with the same thickness of steel plate on the sides.
Modifications
All eight ships had their sailing rig replaced with a pair of light pole masts. ''Partenope'' and ''Minerva'' were reboilered in 1906–1908 and 1909–1910, respectively, with new oil-fired models. ''Partenope''s performance after the refit was from , while ''Minerva'' was faster, at from . During their refits in the late 1900s, ''Partenope'' and ''Minerva'' were converted into
