The 2006 edition of Casa foa took place in the emblematic Palacio Lezama building, located at the intersection of three neighborhoods: La Boca, San Telmo and Barracas. Tres Barrios, Tres Templos pays homage to the three obligatory places of worship in these neighborhoods, the Santa Felicitas Catholic Church, the Russian Orthodox Church and the profane temple of the mouth, La Bombonera.

The polychrome wood sculptures and paper collages arranged in a Zigzag route attempted to account for the overlapping styles, cultures and creeds of these three neighborhoods, showing their architectural and cultural richness.
