Secondly, efforts began to preserve a number of the neighborhoods more famous addresses, mainly by creating independent house museums. Three organizations formed the anchors for this effort, and are still in operation, today. The Confederate Memorial Literary Society formed in 1890 to save the White House of the Confederacy from demolition. In 1896, the CMLS opened what is now the Museum of the Confederacy. In 1892, the Valentine family began its non-profit corporation to create a museum for local history. Its museum, now the Valentine Richmond History Center, opened its doors in 1898. The Association for the Preservation of Virginia Antiquities (now Preservation Virginia) gained its foothold in Richmond by saving the John Marshall House, in 1911. Later efforts by a fourth preservation player, the Historic Richmond Foundation, helped preserve Monumental Church, 1965.
