Hi @sahiba-rana, what a productive walk you had with your mother, this museum is amazing, it has so many spaces to observe, I imagine the tour lasts several hours.
In the area of the gifts to the presidents there must be beautiful works of art, if I had the opportunity to visit this museum I make the most of the time not to miss the beautiful decorative details of this building, especially the ones on the top of the doors, they look like delicate lace made in wood, the ceiling panels are also very attractive, thank you for sharing your visit.
Happy and blessed
