Join Van Gogh's sunflowers as they explore some of their favourite paintings in the gallery, from dramatic battle scenes with rearing horses to god-like portraits and glittering angels.There are loads of secret things to discover about each of the paintings. Some paintings have been stored in castles covered in bat poo, some have been slashed with knives during vandalism, and some are over 400 years old!
