Ca l'Herrando factory is an industrial building located at the foot of the road that goes from Sant Sadurní to link with the Igualada one in Vilafranca. After many refurbishments, its interest lies especially in the façades facing the road. The crowning of the naves with rounded and stepped shapes is interesting, as well as the use of exposed brick and stone fittings.

The factory was built during the present century.

Dye factory with exposed brick façade and stone apparatus. It presents a crowning of the naves with rounded and stepped shapes. The interior is very disfigured by the refurbishments undergone throughout the present century. The façade presents four well-differentiated bodies. The first one to the west, has only one opening to the outside, consisting of a large door covered with a semi-circular arch, made of ingot. The crowning, which roughly follows the shape of the arch of the door, is made with billet battlements, finished in flat tile. The second body is the highest in the building and gives way to a high nave, with a ground floor and two floors. The ground floor has a door and two rectangular windows, elongated vertically. The first floor has three identical windows, while the upper floor is crowned with a straight surface with battlements at both ends, concave pediment in the centre, with a series of narrow vertical rectangular openings. The third body has access through a large covered door with a semicircular arch made of brick, flanked on each side by single pylons for vehicles, offering a hatch for foot access, on its right side. The crowning is done with battlements that trace the shape of the arch of the door. The last part of the building has only one floor and has three vertical rectangular windows. It is crowned by a lintel with battlements at both ends, while in the centre there is a smooth concave pediment. It should be noted that the most modern constructions of the industry were made remembering the finishes of the original building.

The company "Tintes Herrando S.L." was founded by Mr. Manuel Herrando Compte and his brother. It was made exclusively skein dyes. The same company had two other factories, one in Bòbila del Sabater, where spinning heads were made, and another in Sant Quintí de Mediona where the dyeing of crossed coils or "gateau" was done. The raw material, the wool, came from Terrassa and Sabadell. The Sant Pere factory was one of the first to start making permanent white in the textile sector. The factory has been closed since 1989.

By using many acids in the production of the factory, it was a very bad job for the health of the workers. The most interesting thing about the building is the old body.
