Tenango de Doria is renowned for its vibrant Tenango embroidery and textiles. Tenangos (or tenancos) are art pieces which are a part of the municipality's history. It is most notable as it has spread to other parts of Mexico, and the world. Not only that, but the Tenango embroidery style has expanded to be applied to other art mediums. Local artisans in Tenango de Doria have used these colorful designs and applied to them to "barro" (clay) dishware, such as plates and teapots.

Tenango de Doria's center of community is found in its municipal hall that has been renovated over the years. This building decorated with flora and fauna that is depicted in the traditional Tenango style reflects the municipality's identity and community. There are large, colorful, Tenango de Doria letters that are set up in front of the city hall's entrance and library. The street that the city hall is located at is also where weekly "plazas" (markets) are set up: each Sunday, vendors set up their stalls and townspeople join to buy products. These goods range from small toys and ice cream, to fresh fruit and meat, to sponges and shoes.

Other notable features and touristic attractions in this town are the Church of San Agustín, built in 1891, and the cerros (hills) Brujo, el Arco, and el Cirio.
