" The two- or three-story houses have ground-floor walls made out of whitewashed stone or mud, and upper levels of mud and wood. The narrow windows with their scalloped tops have sliding wooden slats to let in light and shut out the rain or the cold. The exterior walls are decorated with elaborate paintings, in faded blues and reds, of lotus flowers, deer, birds, and giant stylized phalluses (“to ward off evil spirits,” Rita says). Ladder steps lead to heavy wooden doors with irregular latches and locks. The roofs are covered with stone slates, or wooden shingles held down by large stones. "
