202 Days

The 21 story, 500-room Hilton Palacio del Rio hotel was designed, completed and occupied in an unprecedented period of 202 working days. Built in 1968 for the Texas World's Exposition, HemisFair on San Antonio's River Walk, the modular construction techniques allowed the pre-built rooms to placed by crane in just 46 days. This view at night shows the River Walk, hotel to the left and lightsabers to right. Canon G11, 1 second @ f/4.5, ISO 200 on a tripod.
