Avenida Alvear is an upscale thoroughfare in Buenos Aires, Argentina. Located in the neighbourhood of Recoleta, it extends for seven blocks, from the Plazoleta Carlos Pellegrini to Alvear Plaza. The avenue is famous not only for the most exclusive representatives of haute couture, but also for its numerous demi-palaces and extensive presence of the French academy architecture so much in vogue in uptown Buenos Aires at the turn of the 20th century. The Buenos Aires Legislature approved the bill to declare it as a Historic Protection Area. A study by the U.S.
