Capitol Theatre, Perth, Art Nouveau theatre in Perth, Australia

The Capitol Theatre was a cinema and theatre at 10 William Street in Perth, designed by George Temple-Poole. Its William Street facade carried a 12.2-by-6.1-metre illuminated sign above the roof, and the lounge foyer and upper crush area had Art Nouveau stencil work. A 4.9-by-3.7-metre chandelier with 300 lights hung inside.

Designed by George Temple-Poole, the Capitol Theatre opened on 4 May 1929, when Mayor James T. Franklin inaugurated it with a screening of Freckles, performances by the Capitol Theatre orchestra, Leah Miller's Beauty Ballet and Syd Roy's Lyricals. In the 1940s and 1950s it hosted formal state and city functions. Thomas Wardle bought it in 1966, Bob Dylan played there that year, and after Wardle sold it in 1968 it was demolished for an office building, before Western Australia had effective heritage legislation.

The opening night on 4 May 1929 mixed the film Freckles with the Capitol Theatre orchestra, Leah Miller's Beauty Ballet and a vaudeville act by Syd Roy's Lyricals. A foyer bust of Rudolph Valentino reportedly had its lips kept red by the kisses of Perth fans; it is now in the Western Australian Performing Arts Museum at His Majesty's Theatre.

The Capitol Theatre stood at 10 William Street, in the block later replaced by an office building, so nothing of the auditorium survives to visit. Its 12.2-by-6.1-metre illuminated sign hung above the roof on the William Street facade, marking the entrance from the street. The Valentino bust from the foyer is now held by the Western Australian Performing Arts Museum at His Majesty's Theatre.

The foyer held a bust of Rudolph Valentino whose lips were reportedly kept red by the kisses of Perth fans; it is now in the Western Australian Performing Arts Museum collection at His Majesty's Theatre. The 4.9-by-3.7-metre chandelier, with 300 lights, hangs today in Melbourne's Princess Theatre.
