Hoysala architecture flourished in the region of present-day Karnataka, India, during the Hoysala Empire's rule from the 11th to the 14th centuries. Known for its intricate and ornate style, Hoysala architecture represents a remarkable blend of Dravidian and Chalukyan architectural elements.

Key features of Hoysala architecture include:

1. **Star-shaped Temples**: Hoysala temples typically have a star-shaped ground plan called the stellate plan, with multiple shrines arranged symmetrically around a central hall. This layout allows for intricate carvings to adorn the exterior walls.

2. **Intricate Carvings**: Hoysala temples are renowned for their exquisite stone carvings, which adorn every inch of the temple's exterior walls. These carvings depict scenes from Hindu mythology, including gods, goddesses, celestial beings, and mythical creatures. The level of detail and intricacy in the carvings is unparalleled, showcasing the skill and craftsmanship of Hoysala artisans.

3. **Lathe-Turned Pillars**: Another distinctive feature of Hoysala architecture is the use of lathe-turned pillars, which are cylindrical in shape and intricately carved with decorative motifs such as floral patterns, geometric designs, and mythological figures. These pillars support the temple's roof and add to its architectural beauty.

4. **Chalukyan Influence**: Hoysala architecture shows significant influence from the earlier Chalukyan style, particularly in terms of the temple's basic layout and structural elements. However, the Hoysalas developed their own unique architectural vocabulary, characterized by a greater emphasis on decorative detail and sculptural intricacy.

5. **Halebidu and Belur Temples**: The Hoysala temples at Halebidu and Belur are among the finest examples of Hoysala architecture. The Chennakesava Temple at Belur and the Hoysaleswara Temple at Halebidu are UNESCO World Heritage Sites and showcase the pinnacle of Hoysala architectural achievement.

Overall, Hoysala architecture is celebrated for its exquisite craftsmanship, intricate carvings, and unique architectural style, making it a significant contribution to India's architectural heritage.
