Glenstone Museum is a museum located on more than 200 acres of rolling hills and unspoiled woodland in Potomac, Maryland. Conceived by founders Mitchell and Emily Rales on their deeply held belief that art is essential to life, it has already become one of the finest collections of modern and contemporary art in the world. In addition to the current museum, when its new museum building opens to the public in 2018, Glenstone will become the largest private museum in America welcoming 100,000 visitors every year free of charge. By thoughtfully integrating the power of art, the energy of architecture and the serenity of landscape, Glenstone is both a distinctive idea and a unique place.
