One of the most interesting features of Rosehill Cemetery is the Gate House. It was built in 1864 using Joliet limestone likely shipped on the I and M Canal. The architect was William Boyington. It has features of a Gothic Castle. These are also seen in his other buildings (the Chicago Water Tower, the Chicago Pumping Station, and the Joliet Prison). The building survived the Chicago Fire. In 1975, it was placed on the National Register of Historic Sites.
