There's something irresistible, almost magnetic, about a gazebo. Come upon one in the middle of a garden or tucked into a remote corner of a yard, and you can't help but stroll toward it. Spend more than a few moments inside and you'll start thinking about adding one to your own backyard. We've assembled a gallery of these links to a more gracious time. They range from small, simple structures to large, elaborate buildings. We'll tell you what's involved in putting one in your backyard, whether you're swinging the hammer, hiring a carpenter or something in between.
