is called the northern portal of Srisailam, and the premier Saiva
kshetra enshrining one of the twelve jyotirlingas according to the
priest. It is a hill temple, built by Kalyana Chalukyas in the
seventh century itself.
Sthalapurana says that Mother Parvathi did penance here,
propitiating Lord Siva and in the end married Him in accordance with
her wish in the presence of Saptamaharshis. The oddity of the hill
is - it is crescent shaped and contains Aalayas both upon it and at
its foot. This Aalaya is described as Guptamaheswaram in literary
lies in the town of Uma Maheswaram of Achchampet taluk of
Mahabubnagar district of Andhra Pradesh.
