A group of German Lutherans from Europe came to the area near 67th and Clarendon Hills Road in 1859. They built the first St. John Lutheran Church and laid out the cemetery behind the church. Today the cemetery is still located at 67th and Clarendon Hills Road. In 1899, a new church was built on the northeast corner of Cass and 75th Street. The Church was located where Taco Bell and Royal Shield Restaurant now stand. In 1969, the second church was torn down and the present St. John's Lutheran Church was built west of Cass and north of 75th Street.

A school was built on the northwest corner of Cass and 75th street in 1860. It was the first Lace School. It is now a museum which is open on the first Sunday of each month from 2:00pm to 4:00pm.

By 1890, the Village of Lace was established. The important location at that time was the triangle bordered by Cass Avenue, Plainfield Road and 75th Street. It was called "The Point." The Point included the Town Hall, General Store, Blacksmith Shop and the office of Dr. Roe. A Post Office had been established at The Point in 1884.

The City of Darien was originally part of these two communities — Lace and Cass. The idea to incorporate came from a desire of some of the residents of four subdivisions to unit into one city. Those subdivisions were Marion Hills, Brookhaven, Clairfield and Hinsbrook.
