Teatro Filodrammatici, Theatre in central Milan, Italy.

Teatro Filodrammatici is a theatre in Milan built between 1798 and 1800 by architect Luigi Canonica, working from a sketch by Piermarini reworked by Pollak, inside the deconsecrated church of Santi Cosma e Damiano. Canonica's hall held about 1,000 seats, with four upper tiers built entirely as loggias rather than separate boxes. The brick facade begun but never finished was replaced in 1904 by the Art Nouveau front by Laveni and Avati that still stands.

The theatre grew out of the small stage of the Collegio de' Nobili, which the Compagnia dei Giovani Repubblicani obtained in 1796 and used for a Guglielmo Tell and Alfieri's Virginia before Bonaparte. Expelled in 1798, the company moved to the deconsecrated church of Santi Cosma e Damiano, where Luigi Canonica built the new theatre, inaugurated on 21 December 1800 with Alfieri's Filippo. In 1805, for Napoleon's coronation as King of Italy, the society became the Accademia dei Filodrammatici and added a drama school.

The academy's name comes from the Accademia dei Filodrammatici, adopted on 26 May 1805, the day Napoleon was crowned King of Italy; it added a drama school. Amateur actors there included Monti and Porta, and Ugo Foscolo was a member. Performances were held on Fridays, when La Scala was closed.

The theatre stands on Via Filodrammatici, a short walk from Piazza della Scala in central Milan. Since Luigi Caccia Dominioni's 1960s rebuild, the auditorium sits nine metres below street level, reached by a curved entrance hall and a sculptural staircase leading to the stalls and two galleries. Look down at the mosaic floors by Francesco Somaini in the foyer on the ground, first and second floors.

The brick facade begun in the 19th century was never completed; the present Art Nouveau front was built in 1904 by the architects Laveni and Avati. A drawing for a facade by Giovanni Giachi also survives. The perimeter walls still correspond to the volume of the old church of San Damiano.
