The tourism industry in Beirut has been historically important to the local economy and remains to this day to be a major source of revenue for the city, and Lebanon in general. Before the Lebanese Civil War, Beirut was widely regarded as the "Paris of the Middle East," often cited as a financial and business hub where visitors could experience the Levantine Mediterranean culture. Beirut's diverse atmosphere and ancient history make it an important destination which is slowly rebuilding itself after continued turmoil. However, in recent times, certain countries, such as the United States, have frequently placed Lebanon, and Beirut in particular, on their travel warnings lists due to the many car bombings and orchestrated acts of political violence.
