The 200-year-old palace of the Travancore maharajas has carved wooden ceilings, marble sculptures and imported Belgian glass. Inside you’ll find Kathakali images, an armoury, portraits of maharajas, ornate thrones and other artefacts. Admission includes an informative one-hour guided tour, though you can just visit the outside of the palace grounds (free), where you'll also find the Chitrali Museum (₹50) containing loads of historical memorabilia, photographs and portraits from the Travancore dynasty.
