9/11 attacks

The national flag of Belgium is seen among international flags installed in the 9/11 Memorial Museum. The installation recalls the flags that flew in the mezzanine level of the original Twin Towers. Some of the flags, which were not on display on 9/11, are part of the museum’s collection.
