The first permanent settlers to the area were Henry Griffith and his wife, Amelia Barrow, both from the Louisiana area. Henry was a cattle rancher, and at one time all of Mont Belvieu was used as pasture land for their cattle. Amos Barber became the second settler, and other settlers followed. After years of owning all of the land Griffith sold the deed to the land known today as Mont Belvieu. Henry Griffith died and was buried with no grave marker; Amelia soon followed. A memorial has been erected at the site of an old oak tree, and there is a rumor that Amelia was buried just down the hill from where their house once stood.
Mont Belvieu has a city hall, several new churches, and the relocated Barbers Hill ISD schools. This area (Eagle Drive) is now the central core of Mont Belvieu’s residential area hosting multiple subdivisions and many “mom & pop” stores. Another core was developed south of the original city along Texas State Highway 146 north of Interstate 10; this core is based mostly on commercial services for Interstate 10 travelers hosting multiple hotels, fast food restaurants, and gas stations. The two cores are connected by the city’s old location (now dubbed “the hill”) which consists mostly of petrochemical company offices and cement slabs of the old city.
