The Robert Hall House is a historic 1830s home on the Walnut Branch. The house was the residence of the early ranger, Robert Hall (1814–1899). It is among the oldest structures still standing in Seguin, Texas. Hall had moved to Texas in 1835 and served with the crew of the Yellowstone during the Texas Revolution. He later joined the regular Texas Army for a six month term on June 1, 1836. He would join the Texas Rangers located near Seguin, who were commanded by Mathew Caldwell, Jack Coffee Hays and Benjamin McCulloch. In 1838, Hall and other rangers co-founded the city of Seguin. Hall married Mary Minerva "Polly" King, a daughter of Colonel John Gladden King and built his home beside the Walnut Branch at what is the northwest corner of present-day Travis and Nolte Streets. From this location he could walk northward along the Walnut Branch and check on his fellow rangers at the Walnut Branch Ranger Station (which was located near the present-day intersection of Court and Guadalupe Streets). Hall also served in the Texas-Indian Wars, Mexican Invasions of Texas, Mexican American War and American Civil War. Locally remembered as the Hall-Burges-Glenewinkel home, this old home stills stands, although somewhat modified from its original log cabin construction.

Sebastopol House Historic Site is an antebellum Greek Revival house built of concrete, located in Seguin, Texas, United States. Joshua W. Young built it between 1854 and 1856 for his sister, Catherine LeGette. Today Sebastopol is one of some 20 surviving buildings that give Seguin the largest concentration of early 19th century structures in the U.S. As a result of its unusual concrete construction, Sebastopol House was included in the Historic American Buildings Survey (H.A.B.S.) in 1936, made a Registered Texas Historical Landmark in 1964, and then listed on the National Register of Historic Places on August 25, 1970. It is a prime example of the limecrete structures of Seguin. The house is constructed entirely of unreinforced cast-in-place concrete and it is one of the oldest and largest structures in the state using this building method. This process was developed and patented by doctor and chemist John Park, who had moved to Seguin in 1846. But he soon had imitators and competitors, contractors like Joshua Young. Often slaves did the hard physical work, using boards to build forms, kept at the right width (12 to 18 inches) by screws and oak spacers when the limecrete mixture was poured into the forms, and allowed to harden. Then the forms were raised another foot or so and the process repeated. A large part of the "Park's concrete" mix was caliche, a thick deposit of gravelly clay that underlies Seguin. Usually the caliche was dug out on site, providing a basement level, as at Sebastopol. The caliche was then mixed with sand, lime made from nearby limestone deposits, and organic materials like straw or horsehair. The exterior walls were usually whitewashed, and the interiors often had woodwork or wainscoting of local walnut, oak or pecan. Joseph Zorn Jr. bought the house in 1874 and it remained in the Zorn family until 1961. Zorn was mayor of Seguin from 1890 to 1910, and played a major role in establishing the first system of free public schools in the town. The Texas Parks and Wildlife Department acquired the house and grounds by purchase in 1976 from the Seguin Conservation Society, which by agreement had preserved the house until the state agency could get funds for the restoration in its budget. Sebastopol was again opened to the public in September 1989. The house is restored to its 1880s appearance. In 2011 ownership was transferred to the City of Seguin.

The Magnolia Hotel is a historic structure located in Seguin, Texas. It was originally built 1840 by James Campbell, as a two room log cabin. It was in operation as a hotel as early as 1844. The building had been in poor repair for a number of years and was added to a list of the most endangered historic places in Texas in 2012. In 2013, the structure came under new ownership of Erin Ghedi and Jim and was being restored for use as a private residence. As of 2019, The Magnolia Hotel is a fully functioning hotel that can be rented out nightly. Tours are also given. It is touted as one of the most haunted hotels in Texas, and many ghost-hunting television shows have been hosted there.

Guadalupe College was a private Baptist college for African Americans in Seguin, Texas. It was established in 1884 and opened officially in 1887. Its founding was chiefly due to the efforts of William B. Ball, who later became its president. David Abner Jr. was president of Guadalupe College from 1891 to 1906, a 15-year tenure during which the college flourished and gained statewide recognition. At its height during his administration, the college had an enrollment of approximately 500 students. Guadalupe College offered a traditional liberal arts program based on classical courses, as well as an "academy" and grammar school, but comparatively little agricultural or trades-based education. It was recognized as a junior college by the Texas Department of Education in 1926 and briefly attained senior college status, from 1929 to 1931, before being adversely affected by the Great Depression. Guadalupe College's main building was destroyed by a fire in 1936 and the college became defunct in 1937 after a fundraising drive was cancelled. Numerous later attempts to reestablish the college were unsuccessful.
