La Alma/Lincoln Park is among Denver’s oldest neighborhoods. La Alma/Lincoln Park dates from the settlement of Auraria City, where the Auraria Higher Education Center is presently located. 93% of the residential blocks were developed before 1900, and the remaining 7% developed between 1900 and 1914. 20 structures within the neighborhood are listed in the Denver Inventory as having architectural or historical significance. Additionally, the neighborhood has a residential district on the National Register of Historic Places. That district, located on Kalamath, Lipan, and Mariposa streets between West 13th Avenue and Colfax Avenue, is an example of early Denver's working class neighborhoods. Prior to 1900, only a few sporadic attempts had been made to develop a park system for the growing city. A notable exception to this was the 15 acre site which the city purchased in 1885 and named "Lincoln Park".
