Rome, also known as the Eternal City, is the capital and largest city of Italy, located in the region of Lazio. As of 2021, it had a population of around 2.8 million inhabitants, making it the fourth most populous city in the European Union. The city is known for its rich history, stunning architecture, and vibrant culture, and attracts millions of tourists each year.

When it comes to the city's night lights, Rome is truly a sight to behold. The city is home to numerous historical landmarks, such as the Colosseum, the Pantheon, and the Roman Forum, all of which are beautifully lit up at night. The iconic Trevi Fountain, located in the heart of the city, is also illuminated, providing a breathtaking spectacle for visitors and locals alike.

However, like many cities around the world, Rome suffers from light pollution. According to recent studies, the city's light pollution levels are quite high, with an estimated sky brightness of 4.4 magnitudes per square arcsecond in the city center. This means that the night sky in Rome is about 1,000 times brighter than what it would be if there were no light pollution.

There are a number of factors that contribute to Rome's light pollution. One major cause is the city's high population density and bustling economy. With so many people and businesses crammed into a relatively small space, there is a constant need for artificial lighting, both for safety and practical reasons. The city's many bars, restaurants, and nightclubs also add to the light pollution, as do the numerous streetlights, billboards, and other illuminated signs that line the streets.

Another factor that contributes to Rome's light pollution is its location. The city is situated in a valley, surrounded by hills on all sides, which can trap light and prevent it from dissipating into the atmosphere. This can exacerbate the effects of artificial lighting and make the night sky appear even brighter than it would otherwise.

Despite the challenges posed by light pollution, there are efforts underway to mitigate its effects in Rome. For example, the city has implemented a number of policies aimed at reducing energy consumption and promoting the use of more efficient lighting technologies. Additionally, there are ongoing efforts to raise public awareness about the issue of light pollution and to encourage individuals and businesses to do their part in reducing their impact on the environment.

Rome is a beautiful and vibrant city, known for its stunning architecture, rich history, and vibrant culture. While the city's night lights are undoubtedly impressive, they also contribute to the problem of light pollution, which can have negative effects on the environment and human health. However, there are steps being taken to address this issue, and with continued effort and cooperation, it is possible to reduce the impact of artificial lighting in Rome and other cities around the world.
