Khambhat also known as Cambay, is a town and the surrounding urban agglomeration in Khambhat Taluka, Anand district in the Indian state of Gujarat. It was once an important trading center, but its harbour gradually silted up, and the maritime trade moved elsewhere. Khambhat lies on an alluvial plain at the north end of the Gulf of Khambhat, noted for the extreme rise and fall of its tides, which can vary as much as thirty feet in the vicinity of Khambhat. Khambhat is known for its halvasan, sutarfeni and kites (patang). And though being a part of sources of oil and gas.
Khambat is perhaps the only place in India, where the Harappan craft – the agate bead making is found in the living tradition. Surprisingly Khambat has no stone deposit. But the craft has survived mainly through acquiring stones from the Rajpipla hills, about 200 km away from the town. In the folklore of Khambat the beginning of the craft is attributed to Baba Ghor, a 1500 AD saint from Ethiopia who had led a large contingent of Muslims to settle in the town. However, in the archaeological record the origin of the craft can be traced to the nearby Lothal, a Harappan outpost flourished about 4000 years ago.
