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.

In 1841, the company Miquel Puig y Compañía was established in Barcelona, with the purpose of making cotton yarn. In 1850 he moved to Esparreguera (Baix Llobregat) where he set up a cotton yarn and fabric factory. Miquel Puig died on September 17, 1863, and was replaced by his son, Josep. The company changed its name to Josep Puig y Compañía. In 1875, they authorised the construction of the Cairat dam and the canal that was to carry the water to the Esparraguera factory. In 1879 Josep Puig died and the company passed into the hands of Antoni Sedó who gave the company a strong boost. During the decade of the 90s of the 19th century, the company manufactured a new product taking advantage of the hydraulic energy production capacity, the calcium carbide intended for obtaining acetylene gas for lighting. In 1897, he requested authorisation for the construction of an industrial canal in Sant Andreu de la Barca that was to allow the company's second calcium factory. After the death of Antoni Sedó, in 1902, his son succeeded him and the new company was called Lluís A. Sedó en Comandita. The new management will start the manufacture of a new product: panes. In 1903, the first hydroelectric power station was built in Catalonia and Spain. During 1912 the calcium carbide factory in Sant Andreu de la Barca was closed. In 1928 Lluís A. Sedó in Comandita bought Tey y Compañía, a silk fabric factory in Rubí (Vallès Occidental). In 1936, they turned the company into a limited company, under the name of Manufacturas Sedó SA. During the decade of the 1950s, the company reached its maximum expansion and in addition to the Esparreguera factory it has one in Rubí, one in Gràcia and another in Sabadell. In 1979, the company presented suspension of payments and began the liquidation process.
