Departments

Peru is divided into 24 regions plus El Callao and Lima Province (or metropolitan Lima city). El Callao is its own region, containing only one province, the Constitutional Province of Callao. Lima Province is the only province in the country that does not belong to any of the other regions. Its capital is Lima, which is also the capital of the country.
