The Cabildo was built under Spanish rule as the seat of municipal government.

Its historical importance became much larger than the government that constructed it.

In 1803, ceremonies connected with the Louisiana Purchase took place here as sovereignty transferred from Spain to France and almost immediately from France to the United States.

The transaction doubled the nominal territory of the young United States.

New Orleans suddenly became part of a republic whose language, legal culture and racial system differed from the city's Creole traditions.

The transition was not simply patriotic expansion.

The Louisiana Purchase included enormous lands inhabited by Native nations that neither France nor the United States had actually settled or controlled fully.

Changing ownership on a treaty did not erase Indigenous sovereignty.

Nor did American rule eliminate New Orleans's French, Spanish, African and Caribbean institutions overnight.

The Cabildo later served as a courthouse.

Plessy v. Ferguson, the case that produced the U.S. Supreme Court's infamous 1896 endorsement of “separate but equal,” emerged from Louisiana's racial order and passed through local courts in this broader civic landscape.

For visitors, the Cabildo can look like one old colonial building beside a cathedral.

Historically, it is a machine for changing legal regimes.

The building survived because each era found a new use for authority inside the same walls.
