The Pontalba Buildings in New Orelans, LA, a national landmark (1849). Flanking Jackson Square, they were built for Micaela Almonester, Baroness de Pontalba. Pontalba led a rather dramatic life after inheriting her father's fortune. She married a cousin 1811, but her new father-in-law attempted to murder her. She attained a separation from her husband, then built the Hôtel de Pontalba in Paris, now the residence of the US Ambassador. Upon the outbreak of the 1848 French Revolution, Pontalba left France for New Orleans. Having spent some of her childhood in the city, Pontalba was distraught to find the French Quarter now in poor condition. She demolished the residences she owned through her inheritance and commissioned a pair of rowhouse buildings.
The Pontalba Buildings were long considered the first apartments in the US, although this was later disproven when it was discovered that it was built as rowhouses. The buildings fell into disrepair under the ownership of Pontalba's decedents, but were renovated starting in the 1930s.
