Edwards Gymnasium and Pfeiffer Natatorium

The Edwards Gymnasium and Pfeiffer Natatorium on the main campus of Ohio Wesleyan University was built in 1905. It was designed by architect J.W. Yost and was built by Feick & Son.

It has a stone entry portico and a "dominant" red tile roof with dormers. The gymnasium is named for alumnus John Edwards of Leipsic, Ohio, who served on the board of trustees of the university and was a major benefactor to the university.

Edwards Hall is a 1,800-seat multi-purpose arena. Located at the south end of the campus in Delaware, Ohio, it is home to the Wesleyan Battling Bishops swimming and handball teams.

In 1985, it was added to the National Register of Historic Places along with the natatorium named for benefactor Annie Merner Pfeiffer.

The Pfeiffer Natatorium was the competition pool for OWU from 1954 to 2010.

Basketball and volleyball competition, and other indoor sports, were moved to the 2,300 seat Branch Rickey Arena, built adjacent to Edwards Gymnasium, upon its completion in 1976.

The Edwards Gymnasium was then renovated to accommodate the Pfeiffer Natatorium, named for donor Annie Merner Pfeiffer.

It is 150x83 ft in plan. Built mainly of light-colored brick, it has a hipped red clay-tiled roof with dormers at both ends and sides.

The entrance has carved stone pillars.

The complex was listed on the National Register as part of a 1984 study of historic resources on the OWU campus. All the OWU sites listed together on the National Register in 1985 are:
