A demolished antenna, an entity "broken" by bureaucracy. Who decides on the heritage of Caltanissetta?

At 5:45 PM on July 23, 2025, on the hill of Sant'Anna in Caltanissetta, a tower nearly three hundred meters tall bent like a reed and then collapsed on itself with a dry thud. The historic Rai Antenna, for decades the vertical sign that stitched the Nisseno horizon to the Sicilian sky, was no more. For some, a gesture due to safety; for others, an avoidable wound. Since then, a question has been traversing the corridors of politics and administrations: who really decides the fate of local heritage? And according to what rules and practices? The Sant'Anna affair is a case study, where the competences of the Sicilian Region, actions of the Superintendencies, municipal acts, administrative courts, the interests of the owner (Rai Way), and public opinion pressures intertwine. And today it also enters the regional parliamentary halls: deputy Valentina Chinnici and the Democratic Party group have submitted an inquiry to shed light on the revocation of the constraint and demolition.

A title that commits: “Who decides?”

To understand who decides, one must start from a premise that makes all the difference in Sicily: the functions regarding the protection of the landscape and antiquities do not fall under the State but, by special statute and subsequent implementing regulations, under the Sicilian Region. A law from 1975 transferred the competences of the peripheral offices of the Ministry to the regional offices—and thus to the Superintendencies for Cultural and Environmental Heritage: a choice that makes the Island a unique administrative laboratory in the country. In this framework, the Superintendencies are territorial branches of the Department of Cultural Heritage and Sicilian Identity and instruct the proceedings on constraints, while the final acts are signed by the competent Regional Department.

Sant'Anna: minimum chronology of an exemplary case

From constraint to revocation

On April 13, 2022, the Sicilian Region imposes the restriction under art. 13 D.Lgs. 42/2004 on the "RAI transmission plant in Caltanissetta" including the tower, tuning cabin, anchors, and historical equipment. Three years later, with D.D.G. n. 2574 of May 28, 2025, the Regional Department of Cultural Heritage revokes that restriction, justifying the decision with "serious structural issues" that emerged after the imposition of protection and referencing art. 128 of the Code. The act is signed by General Director Mario La Rocca; the investigation cites notes from the Superintendency of Caltanissetta dated May 12, 2024 and May 15, 2025.

Meanwhile, the Municipality of Caltanissetta discusses in the council and considers the option of appealing to the T.A.R. against the revocation: a directive act is unanimously voted in June 2025, confirming a cross-party sensitivity on the issue. The opposition and committees such as “Futura – Together We Build the City” and the RAI Antenna Park Association/Committee contest the regional choice, demanding transparency on the documents and assessments.

The Hour of Demolition

In June 2025, Rai Way sets a first date for the demolition; a suspension from the T.A.R. intervenes until July 18; a few days later, on July 14, 2025, the mayor issues an ordinance for the safety management of the area in view of the operations. On July 23, 2025, at 5:45 PM, the tower is demolished with a controlled collapse within the property area, according to the plan signed by appointed technicians. Some local reports indicate July 24, 2025 as the temporal reference; the official communication from Rai Way states the date and time of July 23.

From a technical standpoint, Rai Way refers to checks and consultations: failures at the base insulators in 2017, static screenings with negative results, and in 2024, the report from the Polytechnic University of Milan which identifies demolition as the only solution compatible with site safety and the surrounding urban area. The company announces investments exceeding 1 million euros for the expansion of the regional DAB network.

Politics Re-enters the Field: The Pd Interrogation

In light of the civic mobilizations, the deputy Valentina Chinnici—regional vice-secretary of the Pd—has submitted a question signed by the entire Pd group to the Sicilian Regional Assembly to account for the “lack of investigation,” the timing of the revocation, and the technical-administrative reasons that led to the lifting of the constraint just three years after its imposition. The text references D.D.G. n. 2574/2025, the date of the demolition, and the request for clarifications to the President of the Region Renato Schifani and the Councillor for Cultural Heritage. This is a significant political step because it shifts the focus of the matter from the technical-administrative level to that of institutional responsibilities.
