Royal Wanganui Opera House, Victorian theatre in Whanganui, New Zealand

The Royal Wanganui Opera House is a wooden theatre on St Hill Street in central Whanganui, built in 1899 to plans by Wellington architect George Stevenson. Its lower storey uses Tuscan pillars and pilasters, the upper storey Doric; the auditorium measures 60 by 60 feet and seats 830. Eighteen cast-iron pillars painted to imitate marble support the dress circle, and patrons still avoid seats close to them.

Built in 1899, the theatre stands as one of the oldest wooden theatres in New Zealand and received Heritage New Zealand Category 1 listing status. This recognition acknowledges its importance as an early example of theatrical architecture in the country.

The theatre's name recalls the 1897 proposal by councillor F. M. Spurdle to mark Queen Victoria's record reign with an opera house. Its programme ranges from grand opera and operettas to piano recitals, orchestral concerts, school events, graduation ceremonies, fashion shows, dance and floral theatre. Wedding ceremonies have been held on stage, which can seat a reception of up to 80.

The theatre is located in central Whanganui and is easily reached by car or public transport. Visitors should check the current schedule in advance, as access and tour availability may vary depending on scheduled performances.

The dress circle is held up by 18 cast-iron pillars painted to look like marble; they block sightlines, so regulars still avoid seats close to them. The architect George Stevenson died in July 1899, the day the foundation stone was laid, and retired builder James Tawse took over supervision without pay.
