One of the side temples at Pha That Luang in Vientiane has a large statue of Buddha in front of an enormous door which is one of the most exquisite examples of Buddhist iconography that I've ever seen.
As is shown below, the door is covered in gold bas relief sculptures representing different periods in the life of the Buddha. The amount of detail is amazing, and I spent a long time gazing at this incredible piece of art. The folds on the robes of the five ascetics, the leaves on the Bodhi tree, the deer in the background. [NOTE: The image shows the Buddha's first teaching in the deerpark at Sarnath].
