Gilbreath-Cowsert House. Tennessee native Jeff T. Gilbreath moved his family to this area in 1905. The owner of a local mercantile store, he built this house in 1909. He sold it in 1910 to county attorney Mark Cowsert, whose family lived here until 1912. The house changed ownership a number of times before the Castro County Museum purchased it in 1976. A fine example of early 20th century vernacular housing, it features a bay window and hipped roof with gables. Recorded Texas Historic Landmark-1991 #2185
