The National Gallery of Art, Washington, is one of the youngest major galleries in the world and it is certainly one of the finest. The idea creating such a gallery was first discussed in December 1936, and was only a year later that the work began on the building. From the first, the galley was designed to make use of the modern technology expertise available, to provide not only a superb setting for the works of art it was intended to hold but also to a ensure they were housed in such a way, by the use of devices such as your air conditioning, filter air and even ultraviolet screening panels at the windows, and that the paintings would be perfectly preserved as possible.
