Авенида де Майо
Two important shopping arcades are located on the 100 block: Galerías Boston and the landmark Galería Güemes, designed by Francisco Gianotti and opened in 1914; distinguishable by the illuminated beacon atop its spire, it was one of the tallest buildings in Buenos Aires st the time. The former Gath &amp; Chaves department store (1914) and annex (overlooking Avenida de Mayo) were located here until the retailer's closure in 1974; the buildings today house Banco Meridian, the local branch of Deloitte, as well as Chilean retailer Falabella.
