What is the name of the Island located in San Francisco Bay, 1.25 miles offshore, with facilities for a lighthouse, a military prison, and the Parade Grounds, a large concrete open area?
Parade Grounds The Parade Grounds is a large concrete open area on the south end of Alcatraz Island, off the coast of San Francisco, USA. They lie beyond Building 64. They were originally built in the 1860s on a barren site by the U.S. military who used the site for military drills and parades.
Embarcadero (San Francisco) The Embarcadero is the eastern waterfront and roadway of the Port of San Francisco, San Francisco, California, along San Francisco Bay. It was constructed on reclaimed land along a three mile long engineered seawall, from which piers extend into the bay. It derives its name from the Spanish verb "embarcar", meaning "to embark"; "embarcadero" itself means "the place to embark". The Central Embarcadero Piers Historic District was added to the National Register of Historic Places on November 20, 2002.
