an arbor is an open framework structure that forms a shelter, gateway framework
or bower. Its primary purpose is to be a semi-architectural place for climbing
plants to grow, while providing shaded seating, directional form to frame a view
or to create a private out-of-doors area.
An arbor can be arched or square-topped.
It can be constructed out of materials as diverse as metal, rustic logs, light-weight
concrete, milled and painted lumber, stone and mortar, bundled twigs, bamboo or
even molded plastic. You can make one yourself or purchase pre-constructed arbors.
An arbor differs from a gazebo in that its roof area is open to the elements,
while a gazebo traditionally has a solid roof that protects those seated beneath
it from the elements.
