Final answer:
The Old Minnehaha County Jail's parapet, in a figurative sense, could be symbolically completed by something akin to the installation 'Building Minnesota' that honors the memory of the Dakota warriors. Through visitors' contributions, the artwork provides an ongoing interaction and education, serving as a living memorial and completion of a historical narrative.
Step-by-step explanation:
The parapet of a structure, such as the Old Minnehaha County Jail, is an architectural feature that typically refers to a low protective wall along the edge of a roof, balcony, or other structure. However, the question seems to refer to some form of artwork or commemoration that completes the parapet in a figurative sense. In the context provided, the closest reference to a completion of a parapet through an artwork is discussed in relation to the installation Building Minnesota, created by artist Heap of Birds. This installation honors the 40 Dakota warriors executed during the Dakota Wars, providing a place of remembrance and education about this chapter in history, although it is not located at the Old Minnehaha County Jail and does not serve the purpose of completing its physical structure.
Tribal citizens, by visiting the site, have added personal items like sweat lodge bundles and feathers, effectively completing the installation with their own contributions and engagements. In a broader sense, such contributions and the interaction with the artwork by visitors contribute to a living memorial, symbolically completing the parapet not only of the artwork but also of the historical narrative it represents.
