The Teatro del Mondo was inaugurated in Venice, Italy in 1979
and was one of the installations at the 1980 Venice Biennale.
It was, and still is today, one of the most evocative projects of Aldo Rossi's work. The Theater was built in a basin of Fusina, a small port in the lagoon, on a barge. It was then towed to Venice and moored at Punta della Dogana, on the Grand Canal, in front of Piazza San Marco.
The building consisted of a supporting structure in steel tubes covered with a wooden plank and reached a total height of 25 meters. The main body of the Theater consisted of a parallelepiped with a square base of about 9.5 meters on each side for a height of 11 meters. On its top an octagonal drum supported a pitched zinc roof. Inside, the stage was located in the center, and the public took their places on the sides or in the galleries on the upper floor which could be reached via the stairs on the sides of the parallelepiped.
The theater could accommodate up to 400 spectators of which 250 seated. At the end of the Biennale events, the Teatro del Mondo crossed the Adriatic to reach Dubrovnik. In 1981 the work was dismantled.
