The rays of the set­ting sun find their way in through the intricately carved jali, casting spook­ily geometrical shapes. The patterns come alive as the sun goes down further in the sky, and settles slowly into a dusky kaleidoscope. The natural light-and-shadow show holds me spellbound. At Sarkhej Roza, an elegant architectural complex located in the village of Makarba, about 7 km south-west of Ahmedabad, the elaborate stone lattices take centre-stage.
