California is a census-designated place and community in St. Mary's County, Maryland, United States. The population was 11,857 at the 2010 census, an increase of 27.4% from the 2000 census. California has been growing with the spread of population from the older adjacent community of Lexington Park and the growth in both technology-related and defense-related jobs at the Patuxent River Naval Air Station. There are department stores and numerous shopping centers situated along Maryland Highway 235 ("Three Notch Road").

The Governor Thomas Johnson Memorial Bridge (also referred to as the Thomas Johnson Bridge and the Solomons Bridge) is a 1.37-mile (2.20 km) bridge in Maryland over the lower Patuxent River joining Calvert and St. Mary's counties. The bridge, named for the first governor of Maryland, Thomas Johnson, saw construction start in 1972 and opened to traffic on December 17, 1977. The bridge, carrying an average of 33,000 vehicles a day on Maryland Route 4 (MD 4), is one of two crossings of the Patuxent River in Southern Maryland (the other is the Benedict Bridge approximately 20 miles up river, where MD 231 connects Calvert County and Charles County). The north end of the bridge, on the Calvert side, is located in Solomons. Just prior to the bridge, MD 2-4 narrows from four lanes to two, and MD 2 exits the highway, passing under the bridge and heading toward downtown Solomons. MD 4 continues onto the bridge itself and over the Patuxent River.

St. Richard's Manor is a historic home located at Lexington Park, St. Mary's County, Maryland. It is a 1+1⁄2-story Flemish bond brick dwelling, with a steeply pitched gable roof, constructed before 1750 on the Patuxent River. Also on the property are two tobacco barns built about 1935, and a small pyramid-roofed concrete block pumphouse.On December 16, 1652, "St. Richard's Manor" was re-patented to Luke Gardiner, heir of Richard Gardiner, because the original patent had been lost as a result of the internal strife with Ingle in 1645. Shortly afterwards /_that is in the 1650s _/ Richard Edelen was contracted by Luke to build a second house on the Manor. This house is still standing today on fifty-five acres of the original land patent. Richard Edelen built a second house called "Riverview" (circa 1659) for Luke Gardiner near St. Clements Island. When bequeathing St. Richard's manor, Richard Keene stated "which was taken up in Luke Gardiner's name." This leads one to conclude that Luke Gardiner was given manorial rights and therefore when Richard Keene became possessed of the manor the rights and privileges of Court Baron became vested in Richard Keene as Lord of St. Richard's Manor.St. Richard's Manor was listed on the National Register of Historic Places in 1985.

There are fourteen active lights in the state as well as three automated caissons and eleven skeleton towers replacing previously staffed lights. The first lighthouse in the state was lit in 1822 and the last in 1965 (ignoring automated towers erected later); the oldest surviving structure is the Pooles Island Light and the oldest still active is the Cove Point Light. The tallest extant tower is the Craighill Channel Lower Range Rear Light. If not otherwise noted, focal height and coordinates are taken from the United States Coast Guard Light List, while location and dates of activation, automation, and deactivation are taken from the United States Coast Guard Historical information site for lighthouses. Locations of demolished lights have been estimated using National Oceanic and Atmospheric Administration (NOAA) navigational charts.
