Interesting is there is one common fact between all these prominent temples.
The above temples are Shiva temples. And these temples have located on almost same longitude. They all are located in 79° longitude. These temples exist for thousands of years when no satellite technology was available to measure latitude and longitude of those places. Thiruvanaikkaval is located at around 3 degrees to the south and exactly 1 degree to the west of the northern tip of this divine axis, while Thiruvannamalai is around midway (1.5 degrees to the south and 0.5 degrees to the west).
In fact, Kedarnath temple in the Himalayas is also almost on the same longitude as of these temples.
Kaleshwaram temple (where Lord Siva and Yama are placed on the same platform), and Ramanathaswamy temple at Rameswaram are also almost on the same line.
How people have constructed temples separated by thousands of miles (2383 km between Kedarnath and Rameswaram) on almost same longitude, remains a mystery.
