This is a last outcrop of the Eastern Ghats, with a Bhairavar temple and five peedas in the rocks of the hill called the Pandava Therthams, is also sacred to the Muslims with a dargah of Waliullah Sheikh Abdullah Shaheb on its peak.

The barren hill is believed to have been covered with dense jungle in the days of Maruthupandiar's rule from late 17th century to 1801.

The hilly village includes five areas (Piranmalai Main, Mathagupatti, Pudupatti, Pappapatti, Adiyarkulam).

Piraanmalai is said to be a block of Mount Meru, which got blown off during a fierce tussle between the serpent king Aadiseshan and the wind God Vaayu(as in Tiruchengode).

Lord Shiva in this hill temple is known as Mangaibaagar(also called MangaiNayagar) and Goddess Parvati is known as Thenammal.

In this hill, there is a natural stone carving that depicts the marriage of Lord Shiva and Goddess Parvati .

This is vast complex covering an area of about 30 acres (120,000 m2), with three prakarams (outer courtyard), an attractive Rajagopuram and five beautiful vimanams.
