National Register of Historic Places in Solano County
The Peña Adobe is the oldest building in Solano County.
In 1843, Mexico granted ten leagues named El Rancho Los Putos to Manuel Cabeza de Vaca and Juan Felipe Peña. The original adobe was built on this property in 1842-1843. It was expanded around the year 1864 with a wood frame addition and remodeled around 1880 with a new shingled roof.
In 1958, descendents of Peña and Vaca deeded the adobe and one and a half acres of land to Vacaville for restoration and preservation.
The Historical American Buildings Survey (HABS) documented the adobe with drawings and photographs.
The Peña Adobe is also California Landmark 534.
