History

2026 Landslide

Main article: 2026 Niscemi landslide

On 16 January 2026, a landslide occurred, causing the collapse of Provincial Road 12, which connects Niscemi to the Gela-Catania state road. The mayor had noticed a much larger landslide. ^[7] On January 17, 2026, the Mayor ordered the evacuation of the affected area. 35 people were evacuated for safety, schools were closed, and the Civil Protection Department was already monitoring the area, which presents serious risks of further worsening of the landslide. According to the Civil Protection Department, the landslide has recorded an estimated subsidence of between 6 and 7 meters, moving in the direction of the Maroglio River, with a front measuring 1.6 km and an extension of almost 1 square km. According to initial reports from the Civil Protection, the landslide is already very large. This correct assessment allowed the inhabitants of Niscemi to be saved. ^[8]

Starting on 19 January 2026, with the arrival of strong weather conditions ^[9] , and then on 25 January 2026 with the arrival of Mediterranean Cyclone Harry, which lashed central and southern Italy ^[10] , the landslide situation further worsened. On January 25, 2026, the landslide widened at 1 p.m. and residents fled. The mayor realized the magnitude of the landslide and was already taking all necessary measures to evacuate as many people as possible from the affected area. ^[11]

ISPRA's IdroGEO allows the analysis of the landslide through thematic maps, historical data and satellite and ground monitoring systems, used to follow the evolution of the phenomenon. ^[12]

Monuments and places of interest

The historic center dates back to the second half of the 17th century. Piazza Vittorio Emanuele III is rectangular in shape and overlooks the churches of Santa Maria d'Itria and Addolorata, as well as the Palazzo di Città.

View from the Belvedere terrace in 2016

• Belvedere Terrace: formerly known as Tunnu, is a panoramic terrace built in 1803, ^[14] offering a magnificent view of the Gela plain and the Maroglio River valley. Built in Baroque style at the beginning of the 19th century, it has a rounded shape surrounded by a wrought-iron railing and benches. It represents the final destination of a stroll through the historic center. It was rebuilt in 1921 following damage sustained in a landslide. It was completely destroyed in a landslide in January 2026. ^[15] In the area below the belvedere, a path dedicated to the Italian aviator Angelo D'Arrigo was recently built. ^[16] It offers a panoramic view of the Gela plain.

Education

Niscemi has a municipal library, named in memory of Mario Gori, born Mario Antonino Di Pasquale. Since 2006 located in Via IV Novembre in a 19th-century building. It houses approximately 16,000 cataloged volumes as well as a vast newspaper library. ^[19]

The Civic Museum is housed within the former Convent of the Franciscan Friars Minor. It was born from an idea by Totò Ravalli. Its creation is the culmination of 30 years of active research and the collection of thousands of objects, thanks to the synergy between the Municipality of Niscemi, the Lions Club, the Environmental Education Center (CEA), the Superintendence for Cultural Heritage of Caltanissetta, Europe, and the generosity of private citizens. It was inaugurated on October 7, 2018. ^[20]

World War II

During World War II, Niscemi was the location of Ponte Olivo Airfield, a military airfield used by the United States Twelfth Air Force during the Italian campaign. After the war the area was redeveloped and no evidence of the wartime airfield remains.

American military installation

Main article: Naval Radio Transmitter Facility (NRTF) Niscemi

US Navy Mobile User Objective System (MUOS) Earth Terminal Facility at NRTF Niscemi

Today, there is a military radio station for naval communication, U.S. Naval Radio Transmitter Facility (NRTF) Niscemi. Its tallest antenna is a guyed mast, 252 metres (827 ft) high, situated at 37°7'32"N 14°26'11"E.

The United States Navy installation is the focus of ongoing protest by locally based activist groups, who oppose it and demand its removal on grounds of health (danger from electromagnetic radiation), environmental damage and opposition to the use of armed drones in the Middle East, allegedly guided from this base. ^[21] Allegations of armed drones being operated from this base have never been verified however, as the newly installed MUOS (Mobile User Objective System) ^[22] was intended as an upgrade to legacy communication equipment, and is not intended to communicate with unmanned flying drones. Niscemi inhabitants say the Berlusconi government did not consult them before granting the US the use of the location.
