steep roofs, small casement leaded glass windows (usually due to a scarcity of glass in the colonies), rich ornamentation (in the more expensive house only) and a massive central chimney. French Colonial Developed in French-settled areas of North America beginning with the founding of Quebec in 1608 and New Orleans, Louisiana, in 1718, as well as along the Mississippi River valley to Missouri. The early French Colonial house type of the Mississippi River Valley region was the poteaux-en-terre, constructed of heavy upright cedar logs set vertically into the ground. These basic houses featured double-pitched hipped roofs and were surrounded by porches (galleries) to handle the hot summer climate. By 1770, the basic French Colonial house form evolved into the briquette-entre-poteaux (small bricks between posts) style familiar in the historic areas of New Orleans and other areas. These homes featured double-louvred doors, flared hip roofs, dormers, and shutters. Spanish Colonial Developed with the earlier Spanish settlements in the Caribbean and Mexico, the Spanish Colonial style in the United States can be traced back to St. Augustine, Florida, the oldest established city in the country, founded in 1565. The early type of dwelling in Spanish Florida was the "board house", a small one-room cottage constructed of pit-sawn softwood boards, typically with a thatched roof. Coquina, a limestone conglomerate containing shells of small mollusks, was used as a building stone in St. Augustine as early as 1598 and has been used as recently as the 1930s in construction. There were coquina quarries on Anastasia Island. From these quarries, coquina was brought to build the Castillo de San Marcos, Fort Matanzas, the Cathedral Basilica, and homes throughout Florida's colonial period. Tabby, made of lime, oyster shells, water, ash, and sand, was often poured out to make a hard flooring in these structures. During the 18th century, the "common houses" were whitewashed in lime mortar with an oyster shell aggregate. Typically two-story, the houses included cooling porches to accommodate the Florida climate. The style developed in the Southwest with Pueblo design influences from the indigenous Puebloan peoples architecture. In Alta California, present-day California, the style developed differently, being too far for imported building materials and without skilled builders, into a strong simple version for building the missions between 1769 and 1823. Ranchos were typically built of adobe. Dutch Colonial Developed from around 1630 with the arrival of Dutch colonists to New Amsterdam and the Hudson
