How does the holy sanctum of Brihadeeswara temple, Thanjavur, TN differ from others? - Important features

The 1010 year old Sri Brihadeewara temple, Thanjavur city, TN dedicated to God Shiva (his consort Parvati is  known as Periyanayaki Amman) is a UNESCO recognized World Heritage Monument of exceptional beauty and grandeur. Built by the famous  Chola  ruler Sri Rajaraja I, this huge temple is often referred to as the  Dhakshina Meru (Meru of south).  In this temple the  sanctum is a tall one with a hollow space above it. The tower/gopuram was built ingeniously using interlocking system that considerably  reduces the weight of the overlying structure.

The sanctum sanctorum or Garbagriha (in Sanskrit, garbha meaning womb and griha meaning house ) is traditionally  the innermost sanctuary of Hindu and Jain temples  and it is where the presiding deity in idol form (mostly carved out of stone) is reverentially enshrined as per Agama Sastras. Often referred to as Karauvarai or moolasthanam in Tamil (in Jain temple: the Mulnayaka)  literally the word means "womb chamber",  Generally, in most places across India only qualified 'priests' (pujaris) are allowed to enter this chamber and nobody  is allowed inside. Women priests are rare, and there are some exceptions.  At Haripad  Mannarasala  Sree  Nagaraja Temple, Kerala, the priest is an old woman from the Namboodri family. Sanctum, the most sacred and sanctified  part on the temple premises, is built with single entrance  relative to the size of deity that is placed at the center, and mostly East facing to be accessed by the Sun rays. Normally, it is devoid of a window.
