Sulphur Springs is a city in, and the county seat of, Hopkins County, Texas. It has a population of about 15.500 according to the last census. Sulphur Springs derives its name from the fact that when the area was first settled, springs of sulfur water were abundant. The first settlement was created in 1849. The railroad came to town in 1872 and it grew from there. The city public library has two unique collections: the Leo St. Clair Music Box Collection includes more than 150 unique music boxes, and the Sinclair World War II Collection displays letters, pictures, and other World War II artifacts.
