The National Gallery of Art is located in Washington, D.C. and is managed by the Smithsonian Institution. The building itself is divided into two buildings, east and west, which can be connected by underground passages or across the street on the ground. It also includes a sculpture park. The museum is free to visit and is closed on Sundays.
I originally went there for Leonardo da Vinci's original works, but when I arrived, I found that the exhibition part of Leonardo da Vinci's original works was not open, which was a pity. There are more than 40,000 products in the entire exhibition hall, from the European Middle Ages to the modern era, including oil paintings, sculptures, prints, sketches, etc. There are exhibits. It takes about 1 hour to visit here. There is a coffee shop inside. You can take a map to see the specific location.
