 The suffix "Dome" was also used for the indoor stadiums constructed from the 1960s onward.The official names of those arenas also often included the word "Stadium", such as the Houston Astrodome, whose formal name was "Harris County Domed Stadium" in 1965; the Kingdome, whose formal name was "King County Domed Stadium", and the Metrodome, for which the Minneapolis highway signs directed the driver to "Metrodome Stadium".The retro era of the 1990s and early 2000s saw a return to the original arboreal terms, even to domed structures such as T-Mobile Park and Miller Park.
