The old grist mill...

...is now the Brandywine River Museum featuring the work of the Wyeth family: N.C. Wyeth, his son, Andrew Wyeth, and his son Jamie Wyeth. (Several other less famous Wyeths are also included, as well as a fine collection of American art--from Gilbert Stuart and Howard Pyle to Horace Pippin and Andy Warhol.) It is located in a beautifully rustic setting along the Brandywine River where the Wyeths used to live, and where much of Andrew Wyeth's work is set.
