The first European settlers in this area were French colonists. Their culture still has a big impact on the small city today. These French settlers brought people from Africa to work. Over time, a special group of people called Louisiana Creoles developed. This group included both white colonists of French background and people of color.

The county was named after John Hancock, one of the Founding Fathers of the United States. After the 1830s, more American settlers moved into this area. Even so, many Catholic families still live here. Some of these families have roots going back to both African and French ancestors from the early colonial times. Catholic schools in the area are still popular with students.

Hurricanes and Their Impact

Bay St. Louis has been hit by strong hurricanes. These storms have caused a lot of damage but the city has always rebuilt.

On August 17, 1969, Hurricane Camille hit the area. It first made landfall in Louisiana before moving towards Bay St. Louis.

On August 29, 2005, Hurricane Katrina made its final landfall just west of Bay St. Louis. This powerful storm brought a huge storm surge of about 8.5 meters (28 feet). Because it hit during high tide, the water level was even higher, over 9 meters (30 feet).

Some higher ground in the city, along the old Highway 90, was saved from the worst flooding. This area sits about 7.6 meters (25 feet) above sea level.

Hurricane Katrina damaged many libraries in Mississippi. The Bay St. Louis Public Library had severe roof and water damage. Luckily, it was able to reopen to the public just a few weeks later, on October 12, 2005.

The bridge on US Highway 90 in Bay St. Louis was badly damaged. Many parts of the bridge fell into the water. A new bridge was built to replace it. This new Bay St. Louis Bridge even won an award for transportation. It has a special path for people to walk or bike, featuring art by local artists. The city's underground pipes and utilities were also completely replaced with federal help.
