The country's oldest not-for-profit professional theater doesn't rest on its laurels.. The Scene Founded in 1915, the Cleveland Play House is the oldest non-profit professional theater in the nation and houses three different stages. Productions have ranged from the popular and familiar "Grapes of Wrath" and "Harvey" to lesser-known works, such as "Love, Janis", a rock musical of the life of Janis Joplin and comic-actor-author Steve Martin's play "Picasso at the Lapin Agile." Beware! Children at Plays! While most of its plays are adult-oriented, the Play House also has a separate schedule of low-priced musical theater for school-aged children. For kids and grownups yearning to learn more about performance, the Play House offers classes throughout the year on improvisation, writing, dance and drama. On Saturdays, the Curtain Pullers conduct acting and technical-theater classes for ages 5 and up; and Camp Cleveland Play House offers summer-long creative drama for youngsters ages 5 to 17. Bonus The Play House lobby has transformed into an art gallery of sorts, featuring portraits, photographs and objects d'art to complement the stage productions.
