From Wikipedia: The Kingdom of Mysore was ruled by the Wodeyar dynasty from 1399 until the independence of India in 1947 and the subsequent dissolution of monarchy by the Indian constitution. The Wodeyar kings built a palace in Mysore in the 14th century, but this palace was partially damaged by a lightning strike in 1638. It was repaired and expanded, but fell into neglect by the late 18th century. It was demolished in 1793, and a new palace was built in its place in 1803. This palace was destroyed in a fire in 1897 during the wedding of Princess Jayalakshmanni.
The Queen-Regent of Mysore at the time, Kempananjammanni Vanivilasa Sanndihana, commissioned a British architect, Henry Irwin, to build yet another palace in its place. The architect was requested to combine different styles of architecture in the construction of the palace. The construction was completed in 1912.
