What drives Seguin’s History grade
On its age, its old homes and the National Register, Seguin is more historic than 75% of U.S. towns, #41 of 642 in Texas. Its National Register listings hold the grade up; its share of homes from before 1940 pulls it down.
A−
HistoryA character grade: shown, never part of Seguin’s overall grade.
Few Texas towns list much on the Register (a typical Texas town has 0.0 per 10,000 residents, the U.S. 2.4), so Seguin’s 26.7 sits above most of its state (92% of Texas towns have fewer) while its 90 historic buildings outnumber those of 89% of U.S. towns.
How sure. Graded on any two of the three inputs instead, the letter would range from B− to A. The pre-1940 share (±1.6 points) is firm at this size. Two sources give 1838.

Seguin was the home of Dr. John E. Park, who experimented in construction using concrete made from local materials. The nearly 100 structures—the courthouse, schools, churches, homes, cisterns, walls, etc.—made up the largest concentration of early 19th-century concrete buildings in the United States. About 20 of them remain standing.
The use of concrete largely ended when the railroad arrived in 1876, bringing cheap lumber and the equipment needed for brickmaking. The town had five brickworks, and the wooden buildings of downtown were completely replaced with brick by the beginning of World War I.
