The Theatre Royal has fascinating history that spans over a century. The current building is actually the third theatre to be built. The first theatre, built in 1863 was replaced by an even better theatre in 1876. This too was also replaced by an even grander one in 1908 (the current theatre). It is the only operational Edwardian-style theatre remaining in New Zealand.
With a large auditorium and foyer, traditional horseshoe-shaped dress circle and gallery, elaborate plaster decorative mouldings, Italianate painted dome and marble staircase, the Edwardian theatre is a true masterpiece.
Over the years, the theater has undergone various renovations and upgrades to accommodate modern technical requirements while preserving its historic charm. In recent times, it's most significant challenge was the damage from 2010/11 earthquakes. Over four years, many talented architects, engineers, conservators, craftspeople and a multitude of construction workers joined together to return the theatre to its former glory - even making it better than it was before.
The Theatre Royal bears the name of Lady Diana Isaac, 1921-2012. This is in recognition for her generous support during the 2004/2005 refurbishment.
Throughout its existence, the Theatre Royal has served as a cultural hub for Christchurch, hosting a diverse range of performances. It has been home to theatrical productions, musicals, operas, ballets, concerts, and even film screenings. It stands as a testament to the enduring power of the performing arts and the role they play in enriching lives.
