This temporary exhibition was created with the aim of presenting the works and objects that have entered the collections of the three Sitges museums since 2014. This date marked the reopening of the seafront, Cau Ferrat and Maricel museums. Since then the museums have incorporated 1,382 works, objects and documents, of which a selection of 300 are now on display.

Among the works on display are pieces by Picasso, Isidre Nonell, Ramon Casas, Santiago Rusiñol, Olga Sacharoff and Alonso Cano, as well as one of the largest glass collections in Catalonia, which includes pieces from ancient Egypt to the 18th century.

The first exhibition to compare the three artistic metropolises of the turn of the century: Munich, Vienna and Berlin. As Modernism dawned, the artistic avant-gardes pushed for freedom in both the institutions of art and the subject matter expressed. Many artists within the new currents of Symbolism, Art Nouveau and Impressionism were first presented in the highly regarded Secession exhibitions. This installation comprises more than 200 paintings, sculptures and graphic works by 80 artists. It features not only many artists who can be discovered for the first time, but also foregrounds the oeuvre of Gustav Klimt with numerous examples of his work.

In three acts, the exhibition traces the history of Alphonse Mucha, the king of the printed poster, a symbolic figure of Art Nouveau inseparable from the Paris of the Belle Époque, and shows his major works, including the spectacularly presented Slavic Epic. It also highlights the lasting influence of the artist, a source of inspiration for today's creation, from street art to manga, from cinema to tattooing.

The presentation explores the life and work of Hector Guimard (1867-1942), the French architect and designer whose name is synonymous with the French Art Nouveau movement. Bringing together furniture and design objects including jewelry, metalwork, ceramics, drawings, and textiles from collections worldwide, this is the first major American museum exhibition devoted to Guimard since 1970.

The exhibition is co-organized by the Richard H. Driehaus Museum and Cooper Hewitt, Smithsonian Design Museum.

The installation aims to free Victor Horta of his Art Nouveau label and offer other readings of his work, such as his links with eclecticism and Art Deco. It also focusses on the major role of his masters: architects Alphonse Balat, Eugène Viollet-le-Duc and Joseph Poelaert. The show hopes to liberate Horta's work from all preconceived ideas, painting a portrait of the architect that takes into account all of his contradictions.

The Autrique House presents the work and life of Privat Livemont, an emblematic Art Nouveau artist from Brussels. Working as a versatile artist, a craftsman, and a teacher at the Industrial Academy in Schaerbeek, Livemont seems to have been a tireless worker. He is best known for his posters and the sgraffiti on many facades in Brussels.

With this long-overdue, large-scale exhibition, the Leopold Museum intends to shed new light on the eminent and ground-breaking oeuvre of Max Oppenheimer, which has unjustly fallen into oblivion, and to explore the wealth of his works' motifs. Furthermore, the presentation looks at the role of the artist and his networks through his contemporaries Oskar Kokoschka and Egon Schiele.
