Today Irish culture, much like Haitian culture, has been so engraved in daily New Orleans life that you do not actively notice it. Walking around downtown or uptown, you will often spot an Irish bar. From an architectural side, Irish people have also had a significant impact on the city. James Gallier Sr for example, was an Irish immigrant who lived in New Orleans in the 1800s, and is one of the most influential architects in New Orleans history.

The culture and traditions of the Haitians have had a great effect on New Orleans culture, traditions, and way of life. As is with many other cultures and nationalities, the Haitian population has greatly influenced the architecture, naming of the streets, and the overall feel of the city.

In early June 1721, d’Arensbourg and 300 other German-speaking settlers arrived at Biloxi to establish a settlement– only to discover what was waiting for them wasn't what they expected. The party was incredibly underprepared, since they hadn't possessed nearly enough food or supplies to last long enough. Between March and October 1721, over 700 people arrived at the colony, and over half perished in the following months.

The beginning of German history within New Orleans starts about 25 miles upriver, towards the original German settlements in Southeast Louisiana. It all began when Charles Frederick d’Arensbourg, a German speaking Swedish soldier, took with him 300 men to venture to New France (what would later become Louisiana and New Orleans).
