The auditorium was built in 1912 and underwent a major rebuild and renovation in 1997. It features a large pipe organ, the Hermann Kotzschmar Memorial Organ, donated by Cyrus Curtis and built by the Austin Organ Company (Opus 323). It was renamed in the 1990s following a bequest which allowed the facility to be renovated.[1]
Prime tenants at Merrill are the Portland Symphony Orchestra, Portland Ovations and the Friends of the Kotzschmar Organ. Resident organizations include the Maine State Ballet, Portland Ballet and Opera Maine.
