Did you know that from 1985 to 1990, Six Flags operated a heavily themed theatrical entertainment destination in Baltimore, Maryland? With a Victorian, Jules Verne-esque theme, three attractions (NOT rides) and a very cool use of a real abandoned power plant, the success of Power Plant could've made Six Flags a renowned operator of local attractions (like Merlin is today). Unfortunately, some big missteps caused the place to crumble.

Even worked on by the same folks responsible for many of Disney's best. Here's concept art by Herb Ryman, who was famously tasked by Walt Disney to sketch the very first artwork of Disneyland from scratch.

A very, very cool 4-part series on this long-lost attraction.

I dont get why they were so insistent on no rides when thats the business there in

Interestingly, this was Six Flags second attempt at an indoor attraction. In 1984 they opened AutoWorld in Flint, Mi which failed miserably lasted less than a year. Unfortunately there is little out there on this park.

As for Power Plant, it is too bad it didn't make it. With Steampunk a big thing now, an attraction made to look Vernesc Victorian may have been popular with Steampunk enthusiast.
