In 1811, Cromwell High School occupied the building now used as Belden Library, which is adjacent to the town hall.

Nathaniel White, who died 17 August 1711, was Middletown's second largest landowner, leaving an estate of more than 1500 acres of land, and property.

Nathaniel's will showed he gave 1/4th of his share in the common land to "the schools already agreed upon in the town of Middletown, forever.

He had already been allowing a school to reside on this property, while he was living, and it is the first instance of an American settler donating their land to the government for public use.

Lacrosse, Football, basketball, soccer, cross country, baseball, softball, cheerleading, chorus, school band, volleyball, tennis, golf, debate team, indoor track, and outdoor track and field are the school sports.
