Excerpt:
In Jairpur, the capital of the federal state Rhajasthan situated in the west of India, you will find one of the most timeless and culturally independent pieces of architecture in the world. A place of religion and science still in its own unsecularized integrity, only comparable with the witnesses in stone of the archaic cultures.
The Jantar-Mantar (Sanskrit; translated as “Magical Device”) was built between 1728 and 1734 due to the drafts of Maharaja Jai Singh II (1693 -1743) in the centre of Jaipur, which itself was founded 1727 as new capital city of his principality.
