Nuestra Señora de La Paz is the administrative capital of Bolivia and the second largest city in the country. It is located in the western part of the country in the department of the same name at an elevation of roughly 3,650 m (11,975 ft) (the city is built on steep hills) above sea level, making it the world's highest "de facto" capital city, or administrative capital.
As it grows, the city of La Paz climbs the hills, resulting in varying elevations from 3,000 meters to 4,100 meters (9,840 ft to 13,450 ft). Overlooking the city is towering triple-peaked Illimani, which is always snow-covered and can be seen from several spots of the city, including from the neighbor city of El Alto. - in: wikipedia
