Córdoba, capital of the Argentine province of the same name, is known for its Spanish colonial architecture and vibrant nightlife. It's home to the Manzana Jesuítica, a 17th-century Jesuit complex with active cloisters, churches and the original campus of the National University of Córdoba, one of South America’s oldest universities. The city’s focal point is Plaza San Martín and its neo-Baroque Córdoba Cathedral. Córdoba has many historical monuments preserved from Spanish colonial rule, especially buildings of the Roman Catholic Church. The most recognizable is perhaps the Jesuit Block. The climate of the city of Córdoba, as that of most of the province, is humid subtropical, moderated by the Pampas winds, cold winds that blow from the South-western quadrant, originates in the Antarctica. The first festival of the year is in February, the Carnival, where children enjoy throwing water balloons at each other on the street. Then in the middle of the year, on 20 July, Friends Day is celebrated. Usually, most of the teenagers meet at Parque de las Naciones or Parque Sarmiento and spend the afternoon there. At night, they go dancing to different places, and enjoy a drink. The last festival is Spring Day, held on 21 September, which is Students' Day. Many go to the park or spend the day in the nearby city of Villa Carlos Paz. There they can enjoy lots of activities like concerts, dancing, going down town or visiting the river bank.
