So if it is 5 storeyed it is called “Pancha Tala” Gopuram.
Please read the importance of “Odd Numbers” in Sanatana Dharma.
2 & 3) The front & Back faces of Gopuram & each storey are with the elements related to the Main deity in GarbhaGriha.
Since this is Chadambara Gopuram – elements related to Shiva are seen.
The Side towards North is with Brahma & His Elements. The Side towards South is with Vishnu & His elements.
If it is a Vishnu Temple, the front and Back faces will have Vishnu elements, whereas sides will have Shiva & Brahma elements.
4) The last “Tala” or storey is decorated on all sides with the “Vahana” of the Main deity. Which is visible to devotees from long to decide on which god they will worship.
5) The roof of Gopuram – “Naalaakaara Samunnata Chadhi” is a barrel vaulted roof.
6) The Roof is topped by the “Kalasa” also in odd number always. Here we can see 13 Kalasas.
These are made of copper & attracts the thunderbolts protecting the people & temple.
One important thing is – these Kalasas including the Kalasa on Vimana were filled with the grains to keep the continuity of life on earth in case of Pralaya.
These grains are changed every 12 years – famous with the ritual “Kumbhabhishekham”
