Lima is not just the name of the capital of Peru. The district of Lima where the historical city center is located is called Lima. The surrounding region is called Lima. And to make it a bit more complicated, Lima is also the name of the Province, located in the Department of Lima.
Today Lima forms the region 'Lima Metropolitana'. They divide it into 43 districts (distritos). Thirty of these districts belong geographically to the city of Lima, and each has its own flair, charm and character. Thirteen of Lima's districts are surrounding the core of the urban area and are located outside of Lima in more rural zones. The province of Callao counts with 6 districts that officially belong to the Lima Metropolitan area.
