The house built atop a hill in Swyambhu, a neighborhood west of Kathmandu’s city center, stood at three levels before Saturday. But it couldn’t resist the wrath of the 7.8-magnitude earthquake that struck outside of Nepal’s capital, killing more than 2,500 people and becoming the country’s worst quake in more than 80 years. The earthquake flattened parts of the house, trapping two men side-by-side—one dead, the other alive—for more than 18 hours.
