So What's the Big Deal with the Astrodome?

Every night on the Houston local news they refer to the Astrodome as the 8th wonder of the world. Growing up in Kansas City, I have never heard this before. Was it a momentous feat in its time, or are Houstonians just full of themselves? It just looks like a shitty old stadium to me. I vaguely remember the Kingdome being a big deal, maybe in the early 90's, but they tore that down without much fuss.
