Titusville is a city in and the county seat of Brevard County, Florida, United States. The city's population was 43,761 as of the 2010 United States Census. Titusville is located along the Indian River, west of Merritt Island and the Kennedy Space Center, and south-southwest of the Canaveral National Seashore. It is a principal city of the Palm Bay–Melbourne–Titusville Metropolitan Statistical Area. Near Titusville is the Windover Archeological Site, a National Historic Landmark recognizing its important collection of human remains and artifacts of the early Archaic Period (6,000 to 5,000 BCE.) A secondary, de facto county seat was established beginning in 1989 at Viera, Florida, in the geographic center of the county, to better serve the more populous southern portion of the county. History Indigenous peoples had inhabited this area for thousands of years, as shown by discovery in 1982 of the Windover Archeological Site, dating to the early Archaic Period (6000 to 5000 BCE). It has been designated as a National Historic Landmark because of the significance of its remains. At the time of European encounter, this area was inhabited by the Ais Indians, who gathered palmetto, cocoplum and seagrape berries. They also fished the Indian River, called the Rio de Ais by Spanish explorers. By 1760, however, the tribe had disappeared due largely to infectious disease, slave raids, and the disruptive effects of rum. The United States acquired Florida from Spain in 1821, and the Seminole Wars delayed settlement of portions of the new territory. This community was originally called Sand Point, and a post office was established in 1859, although it closed a few months later. Henry T. Titus arrived in 1867, intending to build a town on land owned by his wife, Mary Hopkins Titus, daughter of a prominent planter from Darien, Georgia. He laid out roads and in 1870 erected the Titus House, a large, one-story hotel next to a saloon. He also donated land for four churches and a courthouse, the latter an effort to get the town designated as county seat. Local history says that Titus challenged Capt. Clark Rice to a game of dominoes to decide the name of the town. Titus won the game, and Sand Point was renamed as Titusville in 1873. The city was incorporated in 1887, the year construction began on St. Gabriel's Episcopal Church, as listed in the 1972 National Register of Historic Places. At one point,
