Work began on Catalan architect Antonio GaudÃ’s Sagrada Familia church in Barcelona in 1883. “Though work resumed in 1952, it has gone very slowly. More than 50 years later, the church is still only 40 percent finished. (It now holds 4,000 people; when it reaches its final circumference, 295 by 196 feet, it will accommodate 14,000.)” It will take at least 30 years more to complete. But for those unwilling to wait to see what it will look like, a new 3-D projection has been completed.
