While this was the earliest public theater in Viterbo, after 1855 it was replaced as the main stage and opera house in town by the Teatro dell'Unione; it is presently shuttered.
In 1719, a merchant with business in piazza delle Erbe, named Bartolomeo Spigaglia, purchased this property behind the church of Santa Maria Egiziaca.
The first work presented on 24 August 1805 was the opera buffa “La serva bizzarra” by Pietro Carlo Guglielmi.
After the opening of the Teatro dell'Unione in 1855, the stage fell into disuse, with only a single performance for the next decade.
It was closed again in 1882 with the new regulations banning indoor public theaters made of wood, because of the risk of fire.
