The Maricel Museum exhibits a complete artistic route from the tenth century to realism and figuration during the first half of the twentieth century, passing through the art collections of Dr. Jesus Perez Rosales and the Collection of Sitges, with works of great quality. The museum exhibition integrates multiple languages, techniques and artistic media in order to achieve a maximum consistency in the chronological sequence of the development of the arts. The museum included works from the collection of Dr. Jesus Perez-Rosales that never had been exhibited in public, acquisitions by the Sitges Heritage Association since 2012 (Ramon Casas, Miquel Utrillo, Arcadi Mas i Fondevila, Artur Carbonell i Augusti Ferrer Pino) ​​and donations from artist’s relatives (Pere Jou and Alfred Sisquella).

Cau Ferrat 's Museum is the workshop that the painter Santiago Rusinol built in Sitges by the sea in 1893 to house its paintings, iron, ceramics, furniture and antique glass. The museum preserves intact the space and works of art that the modernist painter collected. His visit is an invitation to immerse ourselves in the spirit of Modernism and his idea of the creation of total art. On their walls they upload works by their fellow generations such as Ramon Casas, Ramon Pichot, Ignacio Zuloaga or Dario de Regoyos, and young emerging artists from that period such as Pablo Picasso, Manolo Hugue and Isidre Nonell.

The Maricel Palace is one of the most emblematic buildings in Sitges. Forming part of Maricel's artistic ensemble, also receives the name of Maricel de Terra as a differentiation from the museum also known as Maricel de Mar. The Gold Room, the Blue Room, the Chapel Room, the Ship's Room, Terraces or the Cloister, enjoying a splendid view over the Mediterranean, are the main areas that make up the Palace. With a markedly "Noucentista" style, the different rooms are distinguished by a unique decor stressing its character. The Palau currently has a triple function: firstly, as a place that holds very important institutional and cultural events of the utmost importance in the civic and cultural life of Sitges, such as concerts, lectures or presentations. Secondly, some of the areas host events of organizations and companies that rent its use, as well as civil marriages.

La Fundacio Stampfli gathers one of the most important contemporary art collections in Catalonia. Promoted by the couple formed by Pere and Anna Maria Stampfli, the Foundation exhibits in its facilities, located in Placa de l'Ajuntament de Sitges, a selection of the collection composed by 60 works by 90 artists from 22 nationalities. La Fundacio Stampfli was born in 2006 to channel the Stampflis's project that wanted to endow Sitges with a contemporary art center capable of bringing together works from significant artists on the international scene. All the works that make up the collection have been donated by the artists themselves, their descendents or important gallerists and make up, in its entirety, a unique corpus of contemporary art covering the past 50 years.
