The Teatro Olimpico in Vicenza is preparing to undergo one of the most significant restoration and consolidation projects in its recent history. The famous building designed by Andrea Palladio—recognized as a UNESCO World Heritage Site and considered the oldest surviving covered theater in the world—will temporarily close at the end of 2027 to allow for a comprehensive program of work aimed at ensuring its preservation, safety, and its preservation for future generations. The construction project will last approximately one year, during which time the monument will be closed to both visitors and performances, which will be moved to other venues in the city. The project was presented during a meeting held on the stage of the Teatro Olimpico itself by the mayor of Vicenza, Giacomo Possamai; the councilor for Culture, Tourism, and City Attractiveness, Ilaria Fantin; and the councilor for Public Works, Cristiano Spiller. The project will cost 1,745,000 euros, funded entirely by the Ministry of Culture through funds allocated to the Veneto Region for measures to reduce the seismic vulnerability of the entire monumental complex. In addition to this allocation, the City of Vicenza will provide an additional 250,000 euros to strengthen fire prevention measures.
The project’s goal is to protect and enhance one of the Venetian city’s most iconic monuments through a structural consolidation program targeting the most delicate parts of the complex, while ensuring the full preservation of a site that represents one of the finest examples of Renaissance architecture. The restoration is part of a broader national strategy promoted by the Ministry of Culture to prevent and mitigate seismic risk in Italy’s historic buildings—a program launched by Law No. 232 of 2016 and focused on the most significant monuments of the nation’s cultural heritage.
Mayor Giacomo Possamai noted that the Teatro Olimpico had long been in need of a project of this scale. “Thanks to a ministerial grant, we are able to launch this major project, which will allow us to protect, preserve, and pass on intact a treasure such as the world’s oldest covered theater,” he stated. “We are thus moving forward with a process that began several years ago, through which the City of Vicenza has committed to restoring some of the city’s most visited UNESCO sites: the Basilica Palladiana, which hosts major exhibitions, and Palazzo Chiericati, where work is still underway; once completed, we will return to the city a state-of-the-art civic museum featuring a bookstore, a tourist office, and spaces dedicated to the UNESCO site.”
Ilaria Fantin, the councilor for culture, described the ministry’s contribution as a valuable opportunity for the theater’s renewal, announcing the launch of a communication campaign summarized by the slogan “We’re renewing ourselves for the next 500 years.” The theater, she explained, “will close at the end of 2027, so there are still two seasons to enjoy. We’re starting right now to collaborate with associations to ensure that performances can take place at other venues. One of these will be the Canneti Auditorium, which will finally be returned to the city.”
The councilor for public works, Cristiano Spiller, outlined the technical aspects of the project, explaining that the work is designed to ensure the monument’s long-term preservation and significantly reduce its seismic vulnerability. “We will focus primarily on the structural section where Scamozzi’s scenes are located, which a series of surveys identified as the most critical from an earthquake-resistance standpoint,” he stated. “Reinforcements will be installed on the exterior walls, floors, roof, and trusses to ensure the structure can withstand any earthquakes. The funds from the municipality will be used to install a centralized system of infrared digital cameras capable of promptly detecting any signs of fire, thereby enabling immediate and effective response.”
Superintendent Andrea Rosignoli also highlighted the value of the institutional collaboration that made it possible to launch the project. “The initiative,” he noted, “took shape thanks to a virtuous synergy formalized in the collaboration agreement signed on January 18, 2024, between the Superintendence of Archaeology, Fine Arts, and Landscape for the provinces of Verona, Rovigo, and Vicenza, and the City of Vicenza, owner of the Teatro Olimpico. Thanks to this institutional cooperation, the roles and responsibilities of the Superintendency and the municipal administration converge to define a methodological approach focused on seismic prevention to protect Vicenza’s historical and cultural heritage, grounded in an in-depth understanding of the structure. In this way, the Superintendency once again demonstrates its deep commitment to protecting the cultural heritage of the city of Vicenza, of which the Teatro Olimpico is a prime example.”
The restoration project will focus in particular on the complex’s roofing and masonry . The most significant interventions will also involve the famous perspective stages designed by Vincenzo Scamozzi and the so-called “versura”—that is, the part of the theater located beyond the stages, toward the garden, where the floor slabs historically used to support the stage lighting are located.
In the area of the Scamozzi scenes, the cracks in the apse and in the wall facing the garden will first be repaired using the reinforced stitching technique, which involves inserting helical stainless steel bars into the mortar joints. Plans also include stabilizing the southeast wall by connecting the roof to the new structures built during the restoration of the Palazzo del Territorio via an internal truss designed to support the wall.
The roofs will undergo a comprehensive consolidation program. The rafters, false rafters, and continuous wooden beams will be reinforced by inserting laminated wood elements. The entire roof will be stiffened by installing a bracing system consisting of a double layer of plywood panels approximately twenty millimeters thick, connected to the main structure with special screws. At the same time, a steel frame will be installed to serve as perimeter metal bracing, thereby increasing the building’s overall strength. The trusses will also undergo specific stabilization measures aimed at limiting their movement through the insertion of transverse elements. The metal truss beams located in the area in front of the apse will be reinforced using a system of steel cables designed to stabilize the upper portion of the structures.
In the gable area, the project calls for the repair of cracks in the masonry around the first- and second-floor windows, once again using the technique of reinforced stitching with stainless steel helical bars. New metal lintels will also be installed above the windows.
The wooden floors will be reinforced to increase their load-bearing capacity, while the wooden service staircase used to reach the upper levels will be reinforced using metal cables connected to the roof structure and by reinforcing the steps with internal metal profiles. In this area as well, the roof will be reinforced by installing new laminated wood beams positioned beneath the existing ones and by constructing a structural system similar to that planned for the Scamozzi stages, complemented by a perimeter metal bracing system.
Alongside the structural work, a new fire prevention system will be installed, fully funded by the City of Vicenza. The project calls for the installation of digital infrared cameras for night vision, with different specifications depending on the rooms in which they will be placed. The entire system will be managed by a centralized control system that will connect each camera to the fire detectors already installed in the theater, allowing for immediate visualization of the areas affected by any alarms. The system will also enable continuous video recording and real-time monitoring, 24 hours a day, of the complex’s main areas, including the odeon, the anti-odeon, the stage, the backstage areas, the peristyle, the orchestra, and the bleachers.
The project at the Olympic Theater is part of a broader program to protect Vicenza’s monumental heritage, funded by the Ministry of Culture. As part of the same seismic prevention strategy, investments are also planned for other important city monuments, including the cloister and bell tower of the Church of Santa Corona and the Church of Santa Maria Nova. This reaffirms the commitment to extend conservation efforts to the city’s entire historical heritage, ensuring comprehensive protection of its major monumental buildings and guaranteeing that one of Italy’s most significant UNESCO sites can be preserved in the best possible condition for future generations.
