LA Sociedad Protección Mutua de Trabajadores Unidos (SPMDTU) has been awarded three grants that will enable the organization to complete the restoration of its iconic building in the 1925 adobe style. The building sits in the heart of Antonito.

The SPMDTU Concilio Superior Headquarters Building, located on the west side of Antonito’s main street at 603 Main Street, is listed in the State Register of Historic Properties and the National Register of Historic Places in the areas of Ethnic Heritage and Social History.

The scopes of work of these grants include the stabilization and replacement of the roof and the deteriorating northeast corner of the building; restoration of the stage; plumbing and construction of two ADA

These funds will also be used to construct the following energy efficiency measures: an electric service area; electric charging area for visitors to the building; Wi-Fi for internet connection for Zoom and other web-based meetings; solar panels to provide a renewable energy source for the future maintenance of the building; and an apartment for an onsite manager.

Previous grants from the State Historical Fund and the Sangre de Cristo National Heritage Area of Alamosa have funded construction documents and architectural plans (design/engineering), plus the restoration of all 26 outside windows and outside doors and the restoration of the entrance and the vestibule.

The SPMDTU will continue to use general contractor Torres Builders, LLC, and architect  Scheuber and Darden Architects. Both companies know the building well and are well informed with the requirements for the restoration and rehabilitation of historical buildings.

Once the restoration and rehabilitation of the building is complete it will be returned to its splendor in appearance and style of 1925 and will used to host the types of artistic and historic events of the past – that is, musical performances by groups such as Hilos Culturales, art exhibitions, art displays and workshops, dances, weddings receptions, family reunions, and other community events. In addition, once the SPMDTU Museum is established it will be open to the public, tourists and for group tours, thus attracting more interest in the town and in turn having a positive influence on the town and its citizens.

The SPMDTU was founded 122 years ago on November 26, 1900, and is the oldest Hispanic civil rights organization in the United States. It was founded in Antonito, a small town in the San Luis Valley of southern Colorado next to the New Mexico state line, by Celedonio Mondragón and six others to fight discrimination in the fields, mining industry, and railroads. Also, to defend their property rights.

After World War II the SPMDTU had more than 1,500 members. The SPMDTU had concilios locales (local councils or chapters) in 36 towns in northern New Mexico, three towns in Utah and 41 towns in Colorado. They were numbered in order of their founding. Those in Colorado included the following: No. 1 Antonito, No. 2 Capulin, No. 3 Mogote, No. 4 Saguache, No. 5 Ortiz, No. 6 La Isla, No. 7 Los Sauces/Salida, (later became No. 7 in Denver), No. 8 Del Norte, No. 8 Los Valdezes, No. 10 La Jara, No.11 Fort Garland, No. 12 Del Norte/Nos. 8, 30, No. 15 Center/No 41, No. 16 La Garita, No. 17 Lobatos, No. 18 La Jara, No. 19 Alamosa, No. 20 Oak View, No. 21 Ignacio, No. 22 Conejos, No. 24 Pagosa Springs, No. 27 Monte Vista, No. 28 San Pablo, No. 29 Los Pinos/Valle, No. 30 Del Norte, No. 31 Chama, No. 32 Fort Collins, No. 34 Pagosa Springs, No. 35 Durango, No. 36 Montrose, No. 41 Center, No. 45 McPhee, No. 48 Aguilar, No. 49 San Luis, No. 50 Cañon, No. 52 Leadville, No. 54 Garcia, No. 60 Brighton and No. 60 Walsenburg. The three concilios locales in Utah were: No. 59 Clearfield, No. 61 Odgen and No. 63 in Salt Lake City (see page 151-152 of La Sociedad: Guardians of Hispanic Culture along the Río Grande).

Towns in New Mexico that had concilios locales include: No. 4 Rodarte, No. 9 La Madera/ Vallecitos, No. 10 San Miguel, No. 11 Las Tusas, No. 12 Costilla, No. 13 Ojo Caliente, No. 14 El Rito, No. 15 Placitas, No. 18 Ranchos de Taos, No. 20 Ranchos de Taos No. 21 Española Valley ((Española, Alcalde, Velarde, Lyden), No. 23 Lumberton, No. 24 No Agua/ Tres Piedras, No. 25 Chama, No. 26 Española, No. 29 Los Pinos, No. 30 Chamita, No. 30 Ratón and Dawson, No. 32 Arroyo Hondo, No. 33 Las Cruces, No. 34 Chamita, No. 37 Rosa, No. 38 Tierra Amarilla, No. 39 Alcalde, No. 40 Velarde, No. 42 Arroyo Seco, No. 43 Cerro, No. 44 Questa, No. 45 Dulce, No. 46 Embudo/Dixon, No. 53 Taos, No. 57 Nambé, No. 58 Peñasco, No. 63 Amalia, and No. 64 Lyden.

The SPMDTU began as a mutual aid organization that sought, through non-violent actions, to combat the exploitation of Hispanic workers by land barons, mine owners, and the railroads. The organization is still active. Its concilios locales conduct monthly meetings and functions, to further the organization’s vision which is “The SPMDTU is comprised of a diverse group of men and women committed to enriching Hispanic communities and families, with fund-raising efforts aimed at providing and enhancing community services.”
