Groce's Retreat, Jared E. Groce's plantation home in what is now southwestern Grimes County, was built in 1833 when Groce moved to the site on Wallace Prairie, retreating from the malaria of the Brazos River bottoms. The house was located on a three-acre tract twelve miles south of Navasota on an elevation in prairie country that later was part of the farms of S. D. Mason and N. W. Lyles on the east bank of the Brazos River. While residing at the plantation in early 1836, George C. Childress drafted the Texas Declaration of Independence, which was signed at Washington-on-the-Brazos on March 2. President David G. Burnet and his cabinet stayed at Groce's Retreat from March 18 to March 21, 1836, on their way from Washington-on-the-Brazos to Harrisburg; for three days it was thus the temporary capital of the Republic of Texas. William Fairfax Gray described the houses of the plantation as numerous but small and crowded. Groce died there on November 20, 1836. His heirs sold the property to a family named Dunham. The property was later purchased by Dugald McAlpine who built his residence a mile north of the former plantation house. Some of the Groce buildings were standing in 1852. A state historical marker on Highway 6 commemorates the site.
