Former textile factory with several warehouses, chimneys, an aqueduct, houses for the workers and a church with a school. They are simple and functional stone and brick constructions with gable roofs. The preserved chimneys have various shapes, from rectangular to helical. The 1400 HP Turbine Planas is preserved. The Sedó Colony was founded in 1846 by Miquel Puig i Catasús, who built a textile factory o an old flour mill that already existed ("Can Broquetes"). It would grow rapidly until it adopted the characteristics of an industrial colony and, finally, in the 20th century, it would become one of the largest and most important companies in the economic and industrial history of Catalonia. After the death of Miquel Puig (1863), he was replaced by his son, Josep Puig i Llagostera, who started the construction of houses for the workers, expanded the factory and planned various development works. His administrator and substitute, Antoni Sedó i Pàmies, was who would culminate the process of growth and formation of the industrial colony that would bear his name and who developed the entire textile production process. At the same time, he enlarged the workers' colony with new housing for the workers and their families, with the installation of shops, schools, the church, a dispensary, cinema and casino, among others. The workers' colony was located right next to the factory and was structured in elongated blocks of ground-floor and two-storey houses that formed seven parallel streets. In the middle of these parallel streets was the church and, on either side, the schools. After the Spanish Civil War of 1936-1939, the colony reached its maximum growth, but, at the same time, the first symptoms of crisis would begin. Currently, the Sedó colony has been converted into an important industrial estate where there are different companies and industrial activities. The central core of the Sedó Colony Museum is located in one of these industrial spaces.

Large house made up of several buildings and a chapel. It is built of brick and oriented towards the rising sun. The oldest part, corresponds to the current cellar and retains some pointed Gothic arches. The main block is rectangular in plan, has an attached lookout tower and consists of a ground floor and two floors. The main façade has a porch at the entrance and the openings have wrought iron grills. The deck is flat with a balustrade rail. As for the interior, we must highlight the wooden railing of the staircase, with Renaissance and Baroque decorative elements. The patio is from the end of the 19th century – then, it became a garden with Italian sculptures of gods. The origin of the country house dates back to the 14th century. It is known that it already existed in 1350 under the name of Mas d'en Pi. From the 14th to the 18th century, this house was owned, in a direct line, by the descendants of the founder of the manor house, the Comelles family, who had very illustrious characters as guests, even members of royalty. Later, the administration of the property passed to the community of priests of the parish church of Esparreguera. The chapel is from 1717.

The Old Slaughterhouse of Esparreguera is one of Domènech Mansana's works that are conceived on the border between Catalan Art Nouveau aesthetics and Noucentisme. Some construction details and the use of exposed brick framing openings still evoke the modernist sources, but the lack of added decoration and the basilica plan and section of the building are already of a noucentist style. In this way, the property, which occupies an area of 300 m2, consists of three naves separated by columns, the central one higher than the side ones, which are symmetrical. The central nave is covered by a gable roof, while the sides are covered with single-sided roofs. In the main nave, the main façade is arranged with respect to a central axis, where the access door is located, in a pointed arch profiled in brick and green glazed ceramic buttons on the imposts. In the gable there is a large window which is also pointed and is divided into three parts by two mullions. On each front of the side aisles there is a large window with a wavy arch, a form that is repeated in the windows of the side façades. The building also receives natural light from the line of windows that open at the top of the sides of the central nave, which repeat the wavy shape of the lintels and are tripartite with single mullions. The cornices are decorated with lace placed under the eaves, and at the ends of this there are stepped ornaments in the form of corbels. The slaughterhouse stopped functioning as such in 1985. Then it was used as a cultural centre and hosted exhibitions, as well as the castellers, the giants and the devils of Esparreguera. It is Esparreguera's Federation of Entities of Popular and Traditional Catalan Culture, users of this equipment, that bring together the different groups. Josep Domènech Mansana was the son of the architect Josep Domènech i Estapà. In 1917 he was appointed architect of the Ministry of Public Instruction, from where he built schools in Badalona, Argentona, Igualada, Esparreguera, etc. He was also the municipal architect of Esparreguera and Sant Celoni, where he designed the Casa de la Vila, the Athenaeum and the Slaughterhouse, and a professor at the School of Arts and Artistic Crafts in Barcelona.
