Belonging to the 23 Milhas project, the Fábrica das Ideias da Gafanha da Nazaré is the space where the artistic ideas are manufactured. With a continuous and rich program, designed for all types of public, the Factory serves as a meeting point for the local population and brings cultural visibility to this locality.

The Teatro da Vista Alegre was created, almost simultaneously with the factory, for entertainment of workers and residents of the housing project. In 1851 it was rebuilt and decorated with ceilings adorned and curtains adorned. For decades played host to plays, dances and concerts of the Philharmonic from the factory. In 1905 and again in 1970 is the target of renovations that give the current traits. Inactive for many years, only in 1998 was recovered and re-opened. Currently, the space houses a amateur theater group composed of the Vista Alegre factory workers.
