Florida Street becomes San Martín Street one block south of Avenida del Libertador, and beside the best known of Buenos Aires' Art Deco landmarks, the Kavanagh Building. Overlooking Plaza San Martín, the 120 m (390 ft) apartment building was designed in 1934 by the firm of Sánchez, Lagos and de la Tour for Corina Kavanagh. Local lore has it that the wealthy Irish Argentine heiress planned the high-rise as a revenge against the Anchorena family, and made but one demand of the architects: that views of the Anchorenas' Church of the Holy Sacrament from their residence, the San Martín Palace, be blocked.
