The museum of natural history was not built post-1995. It's probably giving that as the date because they added the new planetarium in 2000. Which raises the question, is this true for other buildings -- is it showing the date of the most recent renovation of the building (as opposed to its construction date)?
I believe the way PLUTO is organized is with 1) a value for when the building was first built, and 2) up to two most recent dates of building modification. The building modification data is itself worth exploring in some way, if anyone wants to give that a shot.
This map shows the 'first built' column, so it is strange that they would get the museum of natural history wrong.
