The MAIN is the home for music, comedy, film, theatre, visual art, classes and workshops, meetings and serves as the welcome center for visitors to Old Town Newhall. The venue has been around for 20 years but, as of February 2017 the City of Santa Clarita took over operation and management of the space.

The theater has been transformed into a multi-use arts center including a monthly rotating art gallery, and free programs every Thursday night.

The venue is also available for private rentals, filming and productions.
