The Montalto di Castro Nuclear Power Plant is located in the Lazio region of Italy, near the town of Montalto di Castro. It was designed to have four reactors, but construction was halted in the 1980s due to public opposition and changes in energy policy. The site remains unused, and the partially completed structures are a reminder of Italy's complex relationship with nuclear energy. In 1987, a national referendum led to the decision to phase out nuclear power in Italy, which significantly impacted the future of the Montalto di Castro facility. Today, the site is monitored, and discussions about its potential use or decommissioning continue, reflecting ongoing debates about energy sources in Italy and Europe.
