The dhvajastambha is usually built within the temple walls (prākāra).
They are traditionally built of wood and stone, where the wooden variety is often finished with a metal covering (kavaca).
The dhvajastambha is a common feature in South Indian temples.
[1] Two other objects that are grouped together with this flagstaff are the bali pitham (altar for offerings) and the vehicle (vahana) of the deity to whom the temple is dedicated.
Symbolically, these three objects are shields that protect the sanctuary of the temple from the impure and undevoted.
