arbor = a framework that supports climbing plants; or a shady rest area made by such a framework or by trees and shrubs

As Grandpa held her hand tight and tears rolled down his cheeks, I thought how Granny used to tell me about them camping out under a thick brush arbor their whole first married summer while Grandpa and Uncle Ephraim Toy built her a two-room house out of poplar logs so big it took just five to make a wall.
