About 1/2 hour (10 miles) out of Mysore by car, this small wooden palace is historically fascinating as well as being attractive and evocative of the days when Great Warrior states still held sway over India. The story of Tippu sultan (and his Father's) resistance to the East India Company is discussed (in English) with interesting displays and some fascinating portraits of the local court dignitaries, etched and painted by British artists!
(From here it is only another 1/2 hour drive (10 miles!) will take you to the Brindavan Gardens (and the Hotel restaurant within!). Its a delightful place during the day or at night when it is lit with coloured lights.
This is where the Duke of Wellington defeated and killed the Tipu Sultan after an uprising in 1799. A lot of great paintings inside and the grounds are very pretty.
