Jesús María is south west of Lima's city center. Today it's a lower-middle to upper-middle class, high density district with top rankings in the Human Development Index. Unfortunately like in Miraflores and San Isidro many of the beautiful colonial mansions are being replaced by high-rise apartment buildings.
The main avenues in Jesús María are Av. Salaverry, Av. Mariategui and Av. San Felipe. You find the Ministry of Labour, Health and Agriculture, embassies and consulates, the Apostolic Nunciature, other public institutions, schools and universities in Jesús María.
Worth a visit are the Plaza Cáceres, dedicated to the war hero Andrés Avelino Cáceres, the Iglesia San José (Carmelites church inaugurated 1949) and the Campo de Marte, one of Lima's biggest parks and a great place to chill out, relax or have fun.
