Aula Maxima (Latin pronunciation: [ˈau̯la ˈmaksɪma]), officially the McMahon Hall, is a theatre building in Maynooth, County Kildare, Ireland.

Monsignor James McMahon of the Catholic University of America in Washington, DC originally gifted the building to St Patrick's College, his alma mater,[6][7] and its construction was completed under the presidency of Bishop Robert Browne.

[4] Maynooth University's Drama Society (also known as the Roscian Players) is the resident company of Aula Maxima.

[citation needed] The venue has also hosted performances by St Patrick's College's dramatic society, Maynooth University Chamber Orchestra[8] and Maynooth Community Players:[9] There are numerous stories relating to the reputed presence of a ghost in Aula Maxima.

[citation needed] A number of superstitions exist regarding the Aula Ghost, including one in which the ghost reputedly turns a chair, placed near the Aula Maxima's projection box, to face away from the stage if he does not like a performance or its staging.
