サンクンガーデン
The San Antonio Japanese Tea Garden (also known as the Sunken Gardens) in the U.S. state of Texas was developed on land donated to the city in 1899 by George Washington Brackenridge, president of the San Antonio Water Works Company. The ground was first broken around 1840 by German masons, who used the readily accessible limestone to supply the construction market. Many San Antonio buildings, including the Menger Hotel, were built with the stone from this quarry on the Rock Quarry Road.
