Jambukeshwar Temple, Tamil Nadu

Jambukeswarar Temple, Thiruvanaikaval (also Thiruvanaikal, Jambukeswaram) is a famous Shiva temple in Tiruchirapalli (Trichy) district, in the state of Tamil Nadu, India. The temple was built by Kocengannan (Kochenga Chola), one of the Early Cholas, around 1,800 years ago. It is located in the Srirangam island, which has the famous Ranganathaswamy temple.

Thiruvanaikal is one of the five major Shiva Temples of Tamil Nadu (Pancha Bhoota Stalam) representing the Mahābhūta or five great elements; this temple represents the element of water, or neer in Tamil. The sanctum of Jambukeswara has an underground water stream and in spite of pumping water out, it is always filled with water.

It is one of the 275 Paadal Petra Sthalams, where all the four most revered Nayanars (Saivite Saints) have sung glories of the deity in this temple. The temple has inscriptions from the Chola period.

Wondering how these structures are built so many years back without modern equipments. I don't think we can build these with all the scientific equipments available today.
