Manali village. Over view of slate roofs, note no other roofing materials. The houses are densely packed together. Saving agricultural land? And/or easy access between neighbours in deep snow winters?
Manali village. Slate roof, timber balconies, stone paved courtyards. Gourds climbing on to roofs. In 1970 Old Manali and most villages looked like this. By the 1980s access to new building materials meant rapid change in locations with road access.
