Frank Lloyd Wright's Martin House shared by @cntraveler says: ""American architect Frank Lloyd Wright considered the Martin House one of his most important buildings, and critics agreed. Built for Darwin D. Martin and his family in the early 20th century, the complex exemplifies Wright’s iconic Prairie style, which features horizontal lines and flat roofs. In order to see the house, you’ll have to book a tour in advance; you can choose from several options that range from one hour to a full day exploring all of Wright’s projects in the city."" on Postcard
