One of the architectural features of traditional Lebanese homes is the triple arch--seen here on three levels of an older house on Bliss Street.
Although the triple arch is a typical feature, these old houses are becoming atypical in Beirut--they're evermore likely to be torn down and replaced by high-rise flats that can house 20 families instead of three.
Anyway, back to the picture--I love how each level has it's own style. And those Art Deco ones up on the third floor? Coolest arches ever.
