This is Tipu Sultan’s Palace, Seringapatam, Mysore.
You are not allowed to take photos inside the palace. The photo below is taken by standing outside looking in through the door (a bit naughty, I know, such a tourist I am). Inside are many intricate murals and stories told via paintings, art, colour, patterns and textures. It was quite mesmerizing! I have never seen so many different patterns and colours in one place.
