Banaglore palace will actually remind you of mysore palace to some extent if you are seeing it from left side of the entrance.
Whatever, but the place is actually very good to enjoy the beauty of a palce and get some very classy pictures clicked for your DP.
But wasting your whole day here doesn’t makes any sense, so enjoy the moment you are in there and you can roam inside the palace if you are a history lover or something.
