The refurbishment and restoration of the Teatro Principal de Terrassa implies providing the theatre with a new stalls and a new stage. The shape and layout of the stalls creates a strong sense of proximity between the scene and the audience which is, as a matter of fact, very suitable for the theatrical experience. The refurbishment project also involved the acquisition of a new space, that was annex to the theater, to troubleshoot the access of the staging and to provide the theater with new service rooms. The theater also retrieves the original façade from 1909, the gangway of lobby with the foyer, and in addition, it incorporates the space below the dome. In summary, thanks to the refurbishment, the old theater retrieves the initial prominence.
