Answer: Kalinga architecture
Notes: Kalinga architectural style is a Hindu style of architecture that flourished in ancient Kalinga, which is now the eastern Indian state of Odisha. The style consists of three distinct types of temples: Rekha Deula, Pidha Deula, and Khakhara Deula. The word "Deula" means "temple" in the local language. The three types of temples are classified based on their architectural characteristics:

• Rekha: A tall, straight building that covers the garbhagriha.
• Pidha: A pyramidal-roofed monument.
• Khakhara: An oblong building with a wagon-vault roof.

Some examples of Rekha Deula temples include the Lingaraja Temple in Bhubaneswar and the Sri Jagannath Temple in Puri. The Great Sun Temple at Konark is an example of Pidha Deula. The Mukteswara Temple in Bhubaneswar is a famous example of Kalinga architecture. The temple is dedicated to Lord Shiva and is believed to have been built in the 10th century CE.
