Longtime Forest Parkers already know that beautiful cedar chests were once manufactured in a sprawling brick building on Harrison, but did you know that a former presidential candidate also made his living there?

The so-called Roos property will be the subject of a history lesson this weekend on architectural treasures in the village, and the Edward Roos Cedar Chest Company is certainly a big part of this property’s lore. But there is much more to learn about the structure at 7329 Harrison.

Beginning at 10:30 a.m. March 28, the Forest Park Historic Preservation Commission will host the first in a three-part lecture series on the significant buildings in town. The discussion will be held at village hall, 517 Desplaines, in the council’s chambers and is scheduled to wrap up at noon.
