Cárcel Modelo, also known as Cárcel Celular, was the main prison for men in Madrid at the turn of the 20th century.

Located in the Moncloa-Aravaca district, it was inaugurated in 1884 after seven years of construction[1] and replaced the 18th century Cárcel del Saladero.

The name "Modelo" derived from its standing as a model for other Spanish prisons.

[2] The prison operated through 1939, when it was shuttered and demolished after being damaged during the Spanish Civil War.
