Historic District 
The boundaries of the Gretna Historic District encompass 737 structures and all or a part of fifty-three blocks. The district is located on flat land adjacent to the Mississippi River. It takes in the "old" town of Gretna, and consequently includes all of the buildings one would expect to find in a sizable town of the nineteenth and early twentieth centuries. On the whole, the district has a residential character, although there is a commercial sector near the river. Contributing elements run the gamut from ca. 1845 to 1935. Despite about 25% intrusions and some alteration of contributing elements, the district retains its historic integrity.
With few exceptions the district has a single story scale. Most of the buildings are set close together and fairly close to the street. Public and commercial buildings are set relatively near the river, while residences are located throughout the district.
The Gretna Historic District was listed on the National Register of Historic Places in 1985.
