Rio Grande City Downtown Historic District
Also known as: Rio Grande City
Why it's listed
Rio Grande City's downtown district covers roughly seven blocks east of Britton Avenue, along Main, Second and Mirasoles streets. Founded in 1848 on the site of an earlier Spanish Colonial ranch, the town grew eastward toward Fort Ringgold, and its businesses followed. The district holds 88 contributing and 67 noncontributing resources, mostly shops, houses and combined store-and-home buildings. Many are built of handmade yellow or buff brick, with segmental arch windows, decorative parapets and wrought iron balconies. German mason Heinrich Portscheller shaped much of the finest brickwork, and French immigrants influenced the iron balconies. Later buildings include Queen Anne and Classical Revival houses, bungalows after the railroad arrived in 1925, and Mission Revival commercial structures. Construction largely stopped around 1940, so the district keeps a recognizable historic streetscape. Mexican, American, German and French influences appear together in a small stretch of the border region, which is the reason for the district's recognition.
Significance in brief: The district holds a dense, intact concentration of late 19th and early 20th century commercial and residential buildings. They show a blend of Mexican, American, German, French and other immigrant influences, seen in handmade yellow brick, segmental arch windows and wrought iron balconies. The period of significance ends in 1940, when major construction stopped and the nearby Fort Ringgold was later abandoned.

What listing means for this property
This is a historic district. Buildings within its boundary are either contributing (they add to the district's significance) or non-contributing. Owners of contributing income-producing buildings can claim the 20% federal rehabilitation tax credit; homeowners should look at state credits. National Register districts impose no design review by themselves; a local historic district ordinance, if one exists, does (the difference explained).
