September marks five years since the death of St. Louis creative guru Bob Cassilly, but his unfinished project isn’t forgotten.

After years of probate proceedings, the 55-acre Cementland was released to Cassilly’s heirs in the fall. Now the sole owner, Melissa Giovanna “Gigi” Zompa Cassilly, Bob Cassilly’s widow, is working on plans for the industrial playground’s future.

Giovanna Cassilly is in the process of cleaning up the property and acquiring plans and drawings that Bob Cassilly may have shared with others, according to her attorney, Albert Watkins.

“Plans are being acquired, but Bob was very much a person who did it and then drew up plans, unlike the rest of the world,” Watkins said. “The plan is to fulfill as closely as possible to the ultimate plan, which can only be found in the now-deceased remains of Bob. But we’re going to try to do so with the highest degree of integrity.”
