When visiting Washington D.C., an important attraction to see is the National Gallery of Art.  Here you will find American, British, French, Italian, Northern European, Spanish and many other amazing paintings and sculptures.   One recent acquisition, Bagpipe Player, 1624 was painted by the famous Dutch artist, Hendrick ter Brugghen and is a must see.  As a Washington D.C. translation professional, I can easily spend hours admiring these great works.  Another truly amazing masterpiece is a painting of the Oberwesel, Germany countryside by Joseph Mallord.  When planning to attend make sure you allocate several hours and visit their website for more details.
