The Teatro degli Atti is located in the historic centre of Rimini and is part of a large building complex, the former Augustinians’ Convent wich rose close to the old church erected around 1069 and devoted to Saint John the Evangelist, now known as Saint Augustin Church. The Teatro was inaugurated in 2001. It takes its name from Isotta degli Atti, wife of Sigismondo Pandolfo Malatesta (1470-1468), the famous Lord of Rimini often regarded as the prototype of the Italian Renaissance prince.

It is a modern theater with no curtain, with a seating capacity of 280 including the Stalls and the Gallery. A section of the seating in the stalls can be removed allowing the auditorium to go from seated to flat floor. Moreover the stage, measuring 9,20 metres wide by 6,30 metres deep, can be extended towards the hall, in order to allow different types of shows and staging. Thanks to its porous stone and cherry wood, the auditorium ensures excellent acoustic performances.
The theatre hosts some of the performances included in the music and prose season of the Galli Theatre.
