Inside the Villa there is also the Zoological Station, founded in 1872 by the German naturalist Anton Dohrn; who organized it not only as a scholars' centre but also as a meeting point for intellectuals and artists. It houses the earliest Aquarium in Europe, designed exclusively for the study of fish species living in the Gulf of Naples. The Aquarium is located on the 3rd floor of the building and it is open to the public.

In the middle of Municipal Villa there is the Music Pavilion, built in 1877 with cast iron and glass, following the project by the architect Alvino. For many years this structure had been the attraction for the neapolitan middle class during the summer nights. Inside the pavilion the orchestra played and all around the audience took place and enjoyed the music, with the opportunity to meet and talk with other people.

Behind the Villa Comunale it stretches the road of Riviera di Chiaia, whose most representative building is the Villa Pignatelli, that nowadays houses the Museum of Prince Diego Aragona Pignatelli Cortes, after the donation to the Italian Government done in 1952 by Princess Rosina of Monteleone. Inside the Villa, which is preceded by a beautiful garden, there is a permanent showing of furniture from the 19th century and a space for temporary exhibitions. Here are performed also several concerts of chamber music.
