Lewis Mountain
Lewis Mountain, also known as Onteora, is a historic home located near Charlottesville, Albemarle County, Virginia. It was designed in 1909, and completed in 1912. The house is a three-part plan granite dwelling, consisting of a nearly square center section flanked by one-story, flat-roofed wings in the Colonial Revival style. It features a massive wooden cornice employing a simplified version of the Roman Doric order of Vignola, a deck-on-hip roof with pedimented dormers at its base, and a portico with four Doric order columns. It also has a one-story, tetrastyle Tuscan portico that serves as a
porte cochere. The steeply sloped property features a landscape designed by Warren H. Manning with a series of three terraces with tall dry-laid stone retaining walls.
It was added to the National Register of Historic Places in 2009.
