To talk about this historical administration of Madrid's Puerta del Sol, we would have to go back to the second half of the nineteenth century, after the extensive reform that most of the buildings in the square underwent came to an end in 1865. The first reference to the original owners places Dionisio and Juan Calderón as regular lotteries in 1876, and the premises, known as “Lotería de Calderón”, functioned at the same time as a paper store and a stationery store. The following year, the administration passed into the hands of Enrique Foronda, who handed over the reins of the business in 1914 to Cándida Uría, who already it was announced the following year in the gazettes of the time assuring that its lottery "is the one that gives the most prizes". And it could not be denied that the business was loaded with luck: in 1936, during the Civil War, a bomb exploded in front of the premises without causing any damage. Jumping up to 1959, a time when lottery businesses were run mostly by women, the establishment passes into the hands of a pharmacist, Ángel de Marco, who makes the administration one of the best known in the country, handing out a multitude of prizes. since then. Popularly known as the “Fat Lottery”, the Sol Lottery entered the twenty-first century at the hands of a woman, Paloma de Marco, daughter of the previous lottery.
