Not even roller coasters are immune to mergers. Adventureland — the family-owned amusement park in Altoona, Iowa — has been sold to the subsidiary of an international company.

Palace Entertainment is based in Pennsylvania and operates two dozen entertainment venues in the United States, including Noah’s Ark Waterpark in the Wisconsin Dells. It’s part of a global chain based in Spain. The Adventureland property includes a hotel, water park and campgrounds and is valued at 24 million dollars by the Polk County Assessor. Adventureland opened in 1974 and has 100 rides today. According to a news release from the City of Altoona, the new owners plan to add 10 new rides in the next two years.
