Luna Vashi Temple, Mount Abu, Rajasthan India

The later Luna Vasahi Temple is dedicated to Neminath, the 22nd tirthankar, and was built in 1230 by the brothers Tejpal and Vastupal for a mere Rs 125.9 million. Like Vimal, the brothers were both Gujarati government ministers. The marble carving here took 2500 workers 15 years to create, and its most notable feature is its intricacy and delicacy, which is so fine that, in places, the marble becomes almost transparent.

In particular, the many-layered lotus flower that dangles from the centre of the dome is an astonishing piece of work. It's difficult to believe that this huge lacelike filigree started life as a solid block of marble. The temple remains incredibly well preserved, employing several full-time stone masons to maintain the work.
