The Gallery Entrance area has a series of displays with seating if you wish to sit and look at them. The screenshot opposite is taken whilst standing at the entrance door. Immediately ahead is the Hall of Heroes and through a door on the left is The Library and to the right the Reception Hall. There are four achievement displays in the entrance area and positions for two Paintings.
Directly left of the entrance is a plaque that shows the current museum display count. The Curator's Guide can also be found here.
