Sacramento ( SAK-rə-MEN-toh; Spanish: [sakɾaˈmento], Spanish for ''sacrament'') is the capital city of the U.S. state of California and the seat and largest city of Sacramento County. Located at the confluence of the Sacramento River and the American River in Northern California's Sacramento Valley, Sacramento's estimated 2019 population of 513,625 makes it the sixth-largest city in California and the ninth-largest capital in the United States. Sacramento is the seat of the California Legislature and the Governor of California, making it the state's political center and a hub for lobbying and think tanks. Sacramento is also the cultural and economic core of the Sacramento metropolitan area, which at the 2010 census had a population of 2,414,783, making it the fifth-largest in California.Before the arrival of the Spanish, the area was inhabited by the Nisenan, Maidu and other indigenous peoples of California. Spanish cavalryman Gabriel Moraga surveyed and named the Rio del Santísimo Sacramento (Sacramento River) in 1808, after the Blessed Sacrament, referring to the Eucharist in the Catholic Church. In 1839, Juan Bautista Alvarado, Mexican governor of Alta California, granted the responsibility of colonizing the Sacramento Valley to Swiss-born Mexican citizen John Augustus Sutter, who subsequently established Sutter's Fort and the settlement at the Rancho Nueva Helvetia.

Following the American Conquest of California and the 1848 Treaty of Guadalupe-Hidalgo, the waterfront developed by Sutter began to be developed, and incorporated in 1850 as the City of Sacramento. Sacramento is the fastest-growing major city in California, owing to its status as a notable financial center on the West Coast and as a major educational hub, home of California State University, Sacramento and University of California, Davis. Similarly, Sacramento is a major center for the California healthcare industry, as the seat of Sutter Health, the world-renowned UC Davis Medical Center, and the UC Davis School of Medicine, and notable tourist destination in California, as the site of the California Museum, the Crocker Art Museum, the California State Railroad Museum, the California Hall of Fame, the California State Capitol Museum, and the Old Sacramento State Historic Park. Sacramento International Airport, located northwest of the city, is the city's major airport. Sacramento is known for its evolving contemporary culture, dubbed the most "hipster city" in California. In 2002, the Harvard University Civil Rights Project conducted for Time magazine named Sacramento "America's Most Diverse City".

An arch is a vertical curved structure that spans an elevated space and may or may not support the weight above it, or in case of a horizontal arch like an arch dam, the hydrostatic pressure against it. Arches may be synonymous with vaults, but a vault may be distinguished as a continuous arch forming a roof.

Arches appeared as early as the 2nd millennium BC in Mesopotamian brick architecture, and their systematic use started with the ancient Romans, who were the first to apply the technique to a wide range of structures.
