The square known as Plaça de Joan Corrades i Bosch, which bears the name of the founder of Hostafrancs, houses the smokestack of the former La Porcelana factory, the first plant to manufacture porcelain in Catalonia. Created by the Florensa brothers in 1846, this factory was located next to the road to La Bordeta, on a plot of land that had yet to be developed.

La Porcelana began its production, making home furnishing objects, such as dishes, soup bowls and other materials made with porcelain. However, throughout the 20th century, the company gradually geared its production towards porcelain for light bulbs. The only part of the factory that still stands today is its post-1890 smokestack, which towers above a square building, boasting an octagonal and pyramidal shape, crowned with false openings. Plaça Joan Corrades today is only a part of what was once the factory, which occupied the entire block of houses, until its demolition in the 1970s, following intense neighbourhood protests.
