The second incarnation of the Covent Garden Theatre (now the Royal Opera House), built in ten months in 1808–1809.
It had a symmetrical facade with a tetrastyle portico in the centre, and was the first building in London to use the Greek Doric order.
The portico was flanked by four bays, the end bays being marked by pilasters with a statue in a niche between.
The three bays on each side of the portico had arches on the ground floor and windows above these and a single carved relief above designed 
by John Flaxman.
The main entrance hall, behind the three doors in the portico, was divided into three aisles by square Doric piers.
To the south was the grand staircase, rising between walls, the flight was divided into two sections by a landing, the upper floor had four Ionic columns each side of the staircase that supported a barrel vault over it.
The horseshoe shaped auditorium was on five levels, and seated 2,800 people, not including those in the many private boxes.
The building was destroyed by fire in 1857.
