The Revoltella Museum, located in Trieste, Italy, is an art museum dedicated to 19th and 20th century art. The museum was founded in 1872 by Baron Pasquale Revoltella, who donated his art collection to the city of Trieste with the condition that a museum be built to house it.

The museum's permanent collection includes over 4000 works of art, including paintings, sculptures, drawings, and prints, as well as photographs and videos. The collection is organized chronologically, with the ground floor dedicated to 19th-century art and the upper floors dedicated to 20th-century art.

Highlights of the collection include works by Italian artists such as Umberto Boccioni, Giorgio de Chirico, and Medardo Rosso, as well as international artists such as Gustav Klimt and Egon Schiele. The museum also hosts temporary exhibitions throughout the year.

The building itself is an architectural masterpiece, blending Renaissance and neoclassical styles. The museum underwent a major renovation in the 1960s, which added modern elements to the building, such as a glass and steel staircase.

In addition to its art collection, the museum also hosts cultural events such as concerts, lectures, and film screenings. The museum's location in the heart of Trieste makes it a popular destination for tourists and locals alike.
