Urban aspect
The city of San Juan completely changed its appearance from a colonial one to one of the most modern in the country after the earthquake of 1944, with well-drawn and wide paved streets, ample sidewalks of tiles or mosaics, and lined with acacias, moreras and paradise trees irrigated by quaint canals.
The city is located within the Capital District, which was planned in the form of a checkerboard anchored by Las Heras Avenue (from North to South), 25 de Mayo Av. (East to West), 9 de Julio Av. (east to west) and Guillermo Rawson Avenue (north to south). These four avenues form a perfect rectangle of 16 blocks in width (going from east to west and vice versa -horizontally-) by 10 blocks long (going up and down or North to South, and vice versa). This center of this rectangle is a square of 7 blocks in length by 6 blocks wide, delimited by Leandro N. Alem, Córdoba, Libertador San Martín and Rioja Avenues. This area is the city's downtown and, as such, is the most densely populated and concentrates most of the city's commercial, financial and institutional activities.
The most important perpendicular avenues are Mitre (known for its cinemas and
cyber cafés), José Ignacio de la Roza (built after the 1944 earthquake), commercial Santa Fe Avenue, Rivadavia street (the easternmost two blocks of which have been pedestrianized), and San Martín Avenue (which leads to most access routes towards Greater San Juan). The more important parallel arteries are Mendoza Avenue (leading to
Villa Krause), General
Mariano Acha Av. and Rioja Avenue.
Some of the city's most important landmarks are:
*Cathedral
Designed by architect Daniel Ramos Correa, the cathedral was inaugurated on December 16, 1979. The bell tower is a steeple of 51 meters (170 feet) in height, and features a British clock and a German carillon which sounds every 15 minutes. The interior is accessed through a bronze vestibule crafted
