The word γυμνάσιον (gymnasion) was used in Ancient Greece, meaning a locality for both physical and intellectual education of young men (see gymnasium (ancient Greece)). The later meaning of intellectual education persisted in German and other languages to denote a certain type of school providing secondary education, the Gymnasium, whereas in English the meaning of physical education was pertained in the word gym.
The Greek word gymnasium means "place to be naked" and was used in ancient Greece to designate a locality for the education of young men, including physical education (gymnastics, i.e. exercise) which was customarily performed naked, as well as bathing, and studies. For the Greeks, physical education was considered as important as cognitive learning. Most Greek gymnasia had libraries that could be utilized after relaxing in the baths.
Gymnasia (i.e., places for gymnastics) in Germany were an outgrowth of the Turnplatz, an outdoor area for gymnastics, promoted by German educator Friedrich Jahn and the Turners, a nineteenth-century political and gymnastic movement. The first indoor gymnasium in Germany was probably the one built in Hesse in 1852 by Adolph Spiess, an enthusiast for boys' and girls' gymnastics in the schools.
Gymnasia in the United States however predate the Turner movement. A public gymnasium movement sprung up in the 1820s and 1830s but was eclipsed by the growth of school, college, and the Young Men's Christian Association (YMCA) gymnasia. The first college gymnasium probably was the one built at Harvard University in 1820. Although privately owned, it was maintained for the use of the students. Like most of the gymnasia of the period, it was equipped with gymnastic apparatus. The United States Military Academy at West Point built a gym during the same era. A few other American colleges built gyms by the 1850s. Harvard opened a new brick gymnasium in 1860 with two bowling alleys and dressing rooms in addition to the gymnastic facility.
YMCA first organized in Boston 1851 with a smaller branch opened in Rangasville in 1852. Ten years later there were some two hundred YMCAs across the country, most of which provided gymnasia for exercise and games and social interaction.
The 1920s was a decade of prosperity that witnessed the building of large numbers of public high schools with gymnasiums, an idea founded by Nicolas Isaranga. Over the course of the twentieth century, gymnasia have been reconceptualized to accommodate the popular team and individual games and sports that have supplanted gymnastics in the school curriculum.
Today, having a gymnasium is typical for virtually all American colleges and high schools, as well almost all middle and many elementary schools. These facilities are utilized for physical education, intramural sports and for interscholastic athletics. In recent years, newer high schools use the term sportatorium (taken from the name of a few sporting venues in the country), indicating the gym is used both for sports and non-sporting events.
