Andrew Russell Meem, a graduate of Princeton University and a native of Mt. Jackson, ran the hospital and the land was donated by Col. Levi Rinker, a large slaveowner and one of the wealthiest families in the valley. The hospital, intended as a wayside hospital for intermediate care not a permanent treatment facility for badly wounded, consisted of three two story buildings and could accommodate 500 patients, a mixture of wounded soldiers and those sick from disease. The hospital functioned nearly continuously throughout the war, attending to wounded from the battles of Antietam, Gettysburg as well as the Shenandoah Valley campaigns. In addition, with shifting control of the town some Union soldiers were treated at the hospital and at other makeshift hospitals in the town, including Union Church. A Confederate cemetery was established across from the hospital, directly along the tracks of the railroad. At the end of the war in 1865, Union troops tore down the hospital, using the lumber to build an federal occupation installation on Rude's Hill, 3 miles south of Mt. Jackson. This post was removed in 1875 when the Reconstruction era ended. The Confederate cemetery is all that visibily remains of the hospital today in the town of Mt. Jackson. One of the most notable landmarks in Mt. Jackson, Virginia is the little red brick Union Church in the center of town, built circa 1825, one of the oldest structure in the town. In 1822 an early settler bequeathed to the town a lot to build a nondenominational church for the use of any Christian congregations in the area. A frame church was originally erected on the site, but was replaced by the present brick structure around 1825. The church was used by both sides during the Civil War, including use as a hospital, with etchings on the walls by passing soldiers. Daniel Grey, a Revolutionary War soldier, lays buried here. Many of the most prominent early citizens of the area lay at rest in the church yard. Union Church is on the National Register of Historic Places. The Mount Jackson Historic District encompasses 125 buildings, and contributing structures in the town. This includes a variety of commercial, residential, and institutional buildings dating primarily from the late-19th to the early-20th century, the era of the town's greatest prosperity. They are in a variety of popular architectural styles including Gothic Revival, Federal, and Queen Anne. Other notable buildings include the Stoneburner House, Tisinger House, S. P. Lonas House, Brill Building, Lonas Store, former Peoples Bank (c. 1904), Mt. Jackson Volunteer Fire Department (1936), Mt. Jackson Theatre Building (1938), St. Andrew's Episcopal Church (1876), Mt. Jackson Methodist Episcopal Church (1884), and Triplett Middle School (1925).
