Thursday is the 30th anniversary of the community effort to save the Zeiterion Performing Arts Center in New Bedford.

Director Katherine Knowles tells WBSM News, she believes the "Z" is really the heart of New Bedford.

Knowles says the Zeiterion building itself is close to 90 years old.

She says future plans call for bringing back the ballroom on the building's second floor, and establishing rehearsal halls in the basement.

Knowles says the "Z" is proudly carrying out the same mission spelled out by its founders many years ago.
