La Piedad Cemetery predates McAllen and likely began as a small ranch cemetery in the 1800s. The earliest known burial here is that of Gertrudis Cavazos in 1895. Most of the property was deeded by the Arnold family, and other portions were acquired from the city of McAllen. Those interred here include veterans of military conflicts dating to World War I and veterans of foreign armies. The cemetery features religious iconography, Masonic grave markers, and Woodman of the World markers. It is cared for by the Association del Cementerio La Piedad, which incorporated in 1930 after organizing earlier, and it continues to serve the residents of McAllen today.
