This is the Brooklyn Museum of Art. If you live in Brooklyn, you've probably been there at least once.

BMA is one of Brooklyn's most impressive buildings. But it didn't end up exactly as planned, and in the hundred years since it was built, it has seen some pretty big changes.

In the photo on the left, take a good look at the building as you "spin" it around. How is it different from the architect's original drawing of the museum, shown here?

You might find it easier to spot the differences by comparing the floorplans. Roll your cursor over each version of the building to see its floorplan.

After seeing the floorplans, how would you describe the differences between each version?
