18 de Julio Avenue

Avenida 18 de Julio, or 18 de Julio Avenue, is the most important avenue in Montevideo, Uruguay. It is named after the date when the country's first Constitution was sworn in, on July 18, 1830.

It starts from Plaza Independencia at the limits of the Ciudad Vieja (the Old City), crosses the barrios Centro and Cordón and ends at the Obelisk of Montevideo in Tres Cruces, where it meets Artigas Boulevard. Although not the widest or longest avenue of the city, it is considered as the most important of Montevideo, both as a commercial center and because of the many tourist attractions along its length. It is also the district of Montevideo, as well as Ciudad Vieja, where art deco architecture is best preserved, an example of which is the Rinaldi, Díaz and Salvo palaces.
