Torre CFN, Office building in La Mariscal, Quito, Ecuador

Torre CFN is a 103-metre modernist tower on a plot bounded by Avenida Patria and the streets Reina Victoria, Juan León Mera and 18 de Septiembre, at the southern edge of La Mariscal. Architects Ovidio Wappenstein and Ramiro Jácome designed it with reinforced steel, dark glass and concrete, the last two giving the facade its sober look. It has 23 floors, and the top one holds a dining room with a panoramic view over central and southern Quito.

The building was constructed in 1981 during Ecuador's oil boom, a time of economic prosperity. This growth enabled ambitious building projects and permanently changed the capital's appearance.

The tower's name comes from the Corporación Financiera Nacional, which occupied its 23 floors from early 1982; the state prosecutor's office later took over the building. Its dark glass and concrete facade was meant to signal the oil wealth of the 1970s and 1980s. The top floor holds a staff dining room with a panoramic view over central and southern Quito.

The building sits at the corner of Avenida Patria and Reina Victoria, easy to find in the business district. Visitors can admire the architecture from outside, though access to the interior is limited.

The top floor holds a staff dining room with a panoramic view over central and southern Quito. Before the Attorney General's Office moved in, the tower housed the UNESCO office in Ecuador and the Japanese embassy, and it was the country's tallest modern building for ten years.
