The Royal Opera House opens at Covent Garden, London, England.

The Royal Opera House is an opera house and major performing arts venue in Covent Garden, central London. The large building is often referred to as simply "Covent Garden", after a previous use of the site of the opera house's original construction in 1732.

It is the home of The Royal Opera, The Royal Ballet, and the Orchestra of the Royal Opera House. Originally called the Theatre Royal, it served primarily as a playhouse for the first hundred years of its history.

In 1734, the first ballet was presented. A year later, Handel's first season of operas began. Many of his operas and oratorios were specifically written for Covent Garden and had their premieres there.

The current building is the third theatre on the site following disastrous fires in 1808 and 1856.

The façade, foyer, and auditorium date from 1858, but almost every other element of the present complex dates from an extensive reconstruction in the 1990s.

The Royal Opera House seats 2,256 people and consists of four tiers of boxes and balconies and theamphitheatre gallery.

The proscenium is 12.20 m wide and 14.80 m high. The main auditorium is a Grade 1 listed building as noted by Theatres Trust
