"Scotland’s art collection is spread across three sites: the National Gallery, home to classics by Velázquez and Botticelli; the National Portrait Gallery, including Ken Currie’s haunting Three Oncologists ; and the National Gallery of Modern Art, complete with a stunning sculpture park. The art here proves itself distinct from—and no less treasured than—that on display in London. Pay special attention to the Scottish works, whether by Pop Art pioneer Eduardo Paolozzi or Realist painter James Guthrie (especially his luminous In the Orchard ). The Gallery Bus regularly shuttles visitors between the museums, making it possible to hit all three in one day."
