Bhagandeshwara temple embraces the Kerala style of architecture resplendent with beautiful wooden carvings. The temple premises is kept clean and one does feel serene just being inside the place – which is sorely missing in most of the urban temples of today.
Demon (Rakshash) head outside temples, near the doorways, or at the entrance should have some significance as its a common practice in most South Indian temples I have come across.

The above sculpture is most likely that of Yoga Narasimha (incarnation of lord Vishnu).
Tiled roofing of the temple sanctums. Considering the heavy rainfall this region receives tiled roofing is the most logical choice!
Snakes have an important role in the temple design as at each sanctum’s corner a vigilant Indian Cobra with its raised hood is depicted.
