The tapestries were woven in Flemish workshops based on cartoons connected to Raphael's circle. Many visitors notice an often-discussed optical effect: the eyes of certain figures appear to follow you as you walk past, a much-remarked-on quirk of the weaving technique.

The gallery itself is a long, narrow corridor — visitors tend to move through quickly on the way to the Gallery of Maps, which is a shame given how much detail is packed into each panel. A slower pass rewards a closer look at the smaller border scenes framing each main tapestry.
