The Freer and Sackler galleries are encouraging visitors to take a final peek at Do-Ho Suh’s “Staircase-IV” (at left) as its final weekend on display is fast approaching. The translucent red nylon work is a 1:1 scale reproduction of his New York apartment staircase, complete with architectural detailing.

The artist says the “work starts from a reflection on space, especially personal space. The space I’m interested in is not only a physical one, but an intangible, metaphorical and psychological one.” DCist thinks that with a staircase disappearing into a ceiling, “Staircase-IV” could be a wacky modern interpretation of the Winchester Mystery House.

If you’re heading down to the Freer and Sackler, you should take a look “Caliphs and Kings: The Art and Influence of Islamic Spain” (closes Oct. 17) and “Asia in America: Views of Chinese Art from the Indianapolis Museum of Art,” which opened this past weekend.
