Who was the Spanish alcalde that helped rebuild St. Louis Cathedral?

The correct answer is A. Don Andres Almonester y Roxas. He played a critical role in the rebuilding of St. Louis Cathedral after the devastating fire in 1788 that destroyed much of the city. Almonester, who served as the Spanish alcalde, was a prominent figure in New Orleans and contributed to various infrastructure projects, including the reconstruction of the cathedral, which is one of the city's most iconic landmarks.

His efforts not only focused on the cathedral itself but also showcased his commitment to enhancing the cultural and architectural landscape of New Orleans during Spanish rule. Almonester's contributions extended beyond just this project; he also funded the construction of other significant buildings, such as the Cabildo and the Presbytère, which further solidified his legacy in the city's history.

Other figures mentioned, like Etienne de Bore and William Charles Cole Claiborne, played important roles in the economic and political development of New Orleans but did not directly contribute to the rebuilding of St. Louis Cathedral. Vincent Jose Nunez is less prominently linked to these specific historical events. Thus, it is clear that Don Andres Almonester y Roxas was the driving force behind the cathedral's reconstruction.
