During his stay in London, on 26 May 1970, Yogiji Maharaj expressed his dream that a traditional mandir be constructed in the future. To realise the dream of his guru, Pramukh Swami Maharaj inspired the mandir and consecrated it in 1995. From the moment the first stone was cut on 16 February 1993 to the moment the final piece was packed in June 1995, over 1,500 skilled village craftsmen, artisans from Rajasthan and Gujarat - skilled in traditional stone and masonry - worked round the clock chipping away to fashion the rough stone and fine marble into the required forms. The finished products of rich carvings were a testimony to their exquisite skills of craftsmanship. The Shri Swaminarayan Mandir is the largest of its kind outside of India Stone experts recommended limestone from Bulgaria for the mandir exterior and marble from Italy and Ambaji (India) for the mandir interior. The stone and marble chosen met necessary aesthetic criteria, durable enough to withstand British weather conditions yet soft and suitable enough for the delicate work of carving. The Bulgarian limestone resisted remarkably well the effects of the extreme weather conditions with temperature variations from 30ºC in the summer and dropping to minus 15ºC in the winter. The limestone is very dense, with fine grains and creamy-white in colour. Italian marble is favored for its consistent white coloration, smooth texture and strength. Marble from Ambaji is noted for its snow-white appearance and good finishing. Limestone and marble were transported in consignments by sea to the port of Kandla in Kutch, on the west coast of Gujarat. After the limestone and marble blocks were unloaded, they would be transported by truck to the main workshop in Kandla, some 8km away. It was decided that much of the carving be carried out at Kandla itself for reasons of convenience. A 15 sq km plot was acquired and cleared up and a mini-township built for the craftsmen who would sculpt the stone. Five worksheds were in operation at the Kandla site - one for cutting stones, one for marble work, one for limestone work, one for polishing and one for packing carved materials. It formed what was one of the biggest stone sculpting sites in the world. Over 1,500 skilled village craftsmen from Rajasthan and Gujarat, skilled in stone and masonry work based on centuries of tradition, were involved in the mandir work at 14 different sites in India. www.mandir.org
