From 10 October 1830, to mark Isabel II's ascension to the throne it was changed to Plaza de la Reina.
[2] The area the Plaza Alta occupies has existed since the city was remodeled in accordance with plans the Marquis of Verboom produced.
The first systematic replanning of the area was undertaken in 1807 by General Castaños, Governor of the Campo de Gibraltar.
[4] In the original plans, the western end of the square was raised to provide a level area and the boundaries with the surrounding streets were marked off with chains attached to stone posts.
A year later in 1930, the square was once again remodeled by Mayor Emilio Morillas Salinas, taking on the appearance it has today.
