Description The grey and black tones of the chateau are softened by the gold light spilling from its windows, portrayed in an Impressionist style. The sunset sky at dusk shades from yellow, pale green, and purple, to blue. The sunset is reflected in the river below. Built during the Romantic period in 1515, the chateau of Azay-le-Rideau is among the most beautiful examples of Renaissance architecture in the Loire valley. It exemplifies the traditional French chateau, with its high roofs, turrets, rows of windows, and symmetry.
