In the mid-nineteenth century, Moravian immigrants began moving into central Texas, attracted by fertile soils and the hope for better lives. One who settled here was Pavel Machu (1834-1907), a native of the Vsetin Valley in what is now the Czech Republic. Machu came to Texas in 1870 with his wife, Rozina (Trlica), and their three children, settling first in Austin County.
By 1880, the family resided in Williamson County and, in 1884, Machu donated three acres of his farm for a community school that was named for his native land. S.E. Montgomery donated funds for lumber and built the one-room schoolhouse, which also provided meeting space for church services and community activities.
Moravia School opened in 1884, replacing the earlier Dykes School (1 mi. S). Charles Lord served as the first headmaster. Moravia became Common School District No. 83 in 1903. It continued to serve the dispersed farming settlement and was a focal point for social and religious gatherings. In 1922, trustees enlarged the schoolhouse to two rooms, providing space for grades one through eight. Older students attended high school in Granger.
By the 1930s, the declining agricultural population resulted in the closing of several area schools, and Moravia closed in 1945. The district formally merged with Granger Independent School District in 1949, and the Moravia schoolhouse was soon moved to Granger to the site of Crispus Attucks High School. There it remained until 1964, when the African American Attucks School integrated with other Granger schools. The site of the pioneer schoolhouse now serves as an important reminder of the area's rich cultural history.
