Unmissable on the Havana skyline, the modernist Edificio Focsa was built between 1954 and 1956 in a record 28 months using pioneering computer technology. In 1999 it was listed as one of the seven modern engineering wonders of Cuba. With 39 floors housing 373 apartments, on its completion it was the second-largest concrete structure of its type in the world, built entirely without the use of cranes.

When it fell on hard times in the early 1990s, the upper floors of the Focsa became nests for vultures, and in 2000 an elevator cable snapped, killing one person. Rejuvenated in the 2010s, this Havana giant nowadays contains residential apartments and a top-floor restaurant with spectacular views.
