Originally, the soil on which the current neighborhood was built was a sparsely populated area to the south of the medieval city limits of Madrid. The area fully urbanised to become an
arrabal of the city in the 16th century. The urban grid did not evolve much since then; as until the mid 19th century, when the
plaza de Tirso de Molina was created over the plot made available by the demolition of the convent of La Merced, no noticeable change happened in the grid. In 1435, in response to an outbreak of the plague,
Madrid shut the city gates.
John II of Castile was receiving ambassadors from the
King of France. John fled to
Illescas in Toledo and for their safety, the ambassadors were led to an area outside the city walls, that area is now known as
Embajadores. == Outline ==
