An extensive tract of land purchased in 1843 for colonization by German emigrants. Named for Duke Adolf of Nassau, protector of the emigration society, it was once one of the show places of Texas. Although the 4,428 acres could have been a good half-way station for German colonists on the long journey to western lands, this use was rejected by Prince Carl of Solms-Braunfels, the commissioner general of the "Adelsverein", or German Emigration Society. He feared that the site, which was close to non-German settlements, would cause his people to lose their distinctive national culture. Though never colonized, Nassau became a welcome place for relaxation during trying periods of the emigration movement. Here the prince enjoyed horse racing and held feasts costing thousands of dollars. His successor as commissioner, John O. Meusebach, came to Nassau for less extravagant entertainment. The main dwelling on the plantation was built of oak, two stories high. Even in frontier days it had two glass windows. Cotton was grown on the lands. In 1848 the bankrupt Adelsverein sold Nassau. It was later divided into small farms, cultivated by descendants of the original German pioneers.
