from Wikipedia San José:
San José (Spanish: San José; IPA: [ˌsɑːn hɒˈsɛː]) is the capital and largest city of Costa Rica, and is at the heart of the sprawling Gran Area Metropolitana or GAM, located in the Central Valley. San José is the seat of national government, the focal point of political and economic activity, and the major transportation hub of this Central American nation.
Founded in 1738, San José is one of the youngest capitals of Latin America by its year of foundation, though it was not named capital until 1823. Nowadays it's a modern city with bustling commerce, brisk expressions of art and architecture, and spurred by the country's improved tourism industry, it is also a significant destination and stopover for foreign visitors.
Officially, the city's current population is of 346,799, this population corresponds to the San José Canton, the first of the twenty administrative units in San José Province, though the metropolitan area stretches beyond the canton limits and comprises a third of the country's population. Besides, San José exerts a strong influence on a wider range because of its proximity to minor cities (Alajuela, Heredia and Cartago) and the country's demographic assemblage in the Central Valley.
The city lies at a mean elevation of 1,161 m above sea level, and enjoys a stable climate throughout the year, with an average temperature of 23C and precipitation of 150 mm per month.
The University of Costa Rica was established here in 1843, in that time with the name of "University of Santo Tomás". San José also serves as the headquarters of the Inter-American Court of Human Rights. The city is served by Juan Santamaría International Airport, 23 km west of downtown, in the city of Alajuela.
