The Houston Astrodome is getting attention from the National Park Service but its fate is still in doubt.

The National Park Service has added the "Eighth Wonder of the World" to the National Register of Historic Places.  The move allows developers who may renovate the landmark, access to huge federal tax breaks.  Up to 20% as well as state franchise tax breaks.

The listing does not ensure the survival of the dome however as it only allows incentive for renovation and not immunity from demolition.
