what is the difference between nagar stuyle and dravidian style of architecture
Dravidian style of temple architecture is usually pyramid in shape.As the name itself indicates, these temples are located in southern India mostly in Andhra Pradesh(im happy that these temples are located in my place), Tamil Nadu, Kerala and Karnataka.The architecture basically consists of statues of kings, dancers, warriors,gods(deities) etc.
Nagara style of architecture is mostly found in northern india and these temples are mostly in beehive shape. These temples are found in places like Orissa,Tajasthan, Gujarat etc. Puri Jagannath temple is the best example.
