Cairo is the southernmost city in the U.S. state of Illinois. Several blocks in Cairo comprise the Cairo Historic District, listed on the National Register of Historic Places (NRHP). In 1869 construction began on the United States Custom House and Post Office, which was designed by Alfred B. Mullet.
At the height of Cairo’s prosperity, the post office in the building was the third busiest in the United States. It is one of only seven of Mullet’s Victorian structures remaining in the nation, and the building has been converted for use as a museum. The Old Customs House is also on the NRHP.
Cairo is restoring some architectural landmarks, and plan to develop heritage tourism focusing on the city’s history and relationship to the Mississippi and Ohio rivers. Cairo is open for business. Visit Cairo today!
