in the spring of 1974, the kolmer site was listed on the national register of historic places in two different ways. it was individually added to the register in early may, qualifying because of its archaeological significance, while one month previously it had been added as part of a large historic district. this district, the french colonial historic district, preserves of land connected to early french settlement in the region, and the kolmer site was named one of its most significant contributing properties. among the other contributing properties are truly ancient sites such as the modoc rock shelter and important french or french-influenced structures such as the creole house, the pierre menard house, fort de chartres, and the site of fort kaskaskia, as well as the waterman site where the michigamea lived after their first village was razed.
