They have amazing collection of paintings arranged in the order of period they were painted in. It shows the evolution of art from imaginary miniatures to abstract art form. There is a guided tour at 11 AM,1:30 PM and 4 PM.Its free of cost and a must take. I am from not from art background and he really helped me understand the painting,what to see in it and the evolution of art in India.
Museum is huge will take good 3 hours to make a fair justice to the place.
