Passage: Prince Albert appears within the main arch above the twin entrances, Queen Victoria above the frame around the arches and entrance, sculpted by Alfred Drury. These facades surround four levels of galleries. Other areas designed by Webb include the Entrance Hall and Rotunda, the East and West Halls, the areas occupied by the shop and Asian Galleries as well as the Costume Gallery. The interior makes much use of marble in the entrance hall and flanking staircases, although the galleries as originally designed were white with restrained classical detail and mouldings, very much in contrast to the elaborate decoration of the Victorian galleries, although much of this decoration was removed in the early 20th century. Question: How many levels of galleries do the facades surround?
A:
four levels
