A class of children sitting on the lawn at the Las Vegas Grammar School. The girls are wearing ruffled sun bonnets. Officially called the Las Vegas Grammar School, the complex has informally been referred to as the Fifth Street School almost since its inception, due to its location on Fifth Street (renamed Las Vegas Boulevard in 1959) in downtown Las Vegas. The complex functioned as a school, each year serving between 150 to 200 students in grades first through eighth, until 1966. It sat empty until 1970, when it was converted into Clark County offices. It was acquired by the city of Las Vegas from the county in 1996. Now officially called the Historic Fifth Street School, the building and its site are listed in the National Register of Historic Places and the city of Las Vegas Historic Property Register. Site Name: Las Vegas Grammar School (Las Vegas, Nev.) Street Address: 401 South Las Vegas Boulevard
