Juan Seguin. In 1974, the citizens of Seguin brought the remains of Juan Seguin to this city. On July 4, 1976, the Bicentennial Committee and the City of Seguin reinterred the remains of Juan Seguin in a hillside plot overlooking the Guadalupe River Valley. The site (about one mile southwest of here) is above the old road and ford to the south and was well known to Juan Seguin. His grave is covered with a marble slab and the site is a part of the city park system. #2876
