The region where the current parish stands was a fertile plot of land next to the Nalón river, including structures such as the 15th century "Casa de los Notarios," demolished in 2019.

[4] In the last quarter of the 19th century, during the Restoration period, Antonio María Dorado, a local conservative politician, who was mayor of Langreo for a total of 18 years on an intermittent basis, was of particular importance in the town.

He had a special interest in consolidating the urban system of Sama, opening streets and squares, regulating the weekly market, building the new town hall and the parish church, bringing water to the public fountains and strengthening municipal power.

Industrial activity in Langreo, similar to that which characterized Sama, continued to favor the demographic growth of the town, which, although less than that of its neighbor La Felguera, turned it into one of the largest urban centers in Asturias.

[5] After the Spanish Civil War, the era of autocracy was beneficial for the economy of the region, but it lost importance with the creation of Aceralia and the progressive transfer of industrial activity to other parts of Asturias.

In 2007, a fire on an underground coal transport belt to the Modesta Washhouse made it necessary to evacuate hundreds of residents of the town due to a cloud of toxic gas.

[6] Today the industrial and economic crisis of the mining regions has reduced the commercial activity that characterized Sama until a few decades ago, also affecting its demographic weight, going from the 15,000 inhabitants it once had to the current 8,500.
