Following extensive renovations, the County Hall was transformed into the Mullingar Arts Centre which opened officially on November 19th 1998 with the first programme of events being launched in February 1999.

The Arts Centre provides workshops in Art, Music, Dance/Ballet, Crafts, Drama ( for adults, children, disadvantaged and those with special needs).

The Centre is all-inclusive.

It is the policy of the Centre to provide buses for rural school children to all children's events. The Centre organises the buses and shows for the schools. The Arts Centre has also initiated an Arts Education Programme which was initially targeted towards rural schools. This programme covers all areas of the arts: Music, Art, Dance, Photography, Literature, Drama, technical aspects of theatre, including sound, lights, stage management etc.

The accommodating acoustics of Mullingar Arts Centre sees renowned artists performing in the Centre.

Those who have performed to date include, Des Bishop, Christy Moore, Paul Daniels, Hal Ketchum, Mary Black, P.J. Gallagher, Michael English, Keith Barry, Phil Coulter and a host of other National and International performers.

Opera is proving to be a growing area of culture within the Midlands area and all performances to date have been hugely successful.  

European Ballet, Ballet Gwent and Theatre Productions have performed exciting works in the Centre to great acclaim. Modern Dance was also performed by John Scott's Irish Modern Dance Company and Daghda Dance Company.

Most professional companies in Ireland have performed in the Centre. This comprises popular drama as well as classical and contemporary theatre. Children's Theatre is also catered for, in particular by the ever popular Barnstorm Theatre Company and Dublin City Theatre.
