Founded by German immigrants in 1872, the church was officially established the German Evangelical Lutheran Zion Church on Sept. 4, 1881. Today known as Zion Lutheran, the church, a member of the Evangelical Lutheran Church in America, has a congregation of more than 1,200 people. It has been on its current site since 1955; the old church is currently home to the Tinley Park Historical Society. Communion services are held at 5pm on Saturdays and at 8:30am and 11 am on Sundays. (During the summer months, the later morning service is held at 10am instead of 11am.) Also on Sundays, a contemporary service designed as a "seekers service" for new churchgoers is held at 9:45am.
