Silathoranam

 Silathoranam

One of the natural marvels that history left behind, the Silathoranam, now, finds itself being an important landmark in archaeology and heritage. This is a natural rock formation, one of the only three of this kind in the world.

While geology and archaeology foster a number of theories, the rock formation is also tied to beliefs of its connection with the idol of Lord Venkateswara. The rock formation is a national monument and is protected by the State Government.

With a height of 3 meter and width of 8 meter, it presents a captivating view. According to geological findings these rocks belong to the pre-Cambrian era and about 1.5 billion years old; suggesting billion years of history of Tirumala hills as well. It was in 1980s when geologists had found out that two different rock sets are connected through an exceptionally thin link.

Another important feature of Sila thoranam is its exclusivity. According to Geologists, there are only two other sites in the world with similar features. One rock formation is in UK that cuts through the cape of Dalradian Quartzite while the second one is in USA- Rainbow Arch Bridge of Utah.
