Plaza de San Antonio Monument · Aranjuez, Las Vegas, Madrid The plaza de San Antonio, also known as the plazuela de la Mariblanca, is an arcaded square designed by Santiago Bonavía around 1750 as the first urban nucleus of the Real Sitio de Aranjuez; its arcaded galleries, completed by Jaime Marquet after the architect's death, link the Casas de Oficios y de Caballeros with the Casa de Infantes, and the church of San Antonio and the garden of Isabella II also open onto it. Its popular nickname comes from the fountain of Venus, known as the Mariblanca, which adorns its northern end, a work by Juan Reyna installed in 1762; before that there stood another fountain there, that of the King, with an image of Ferdinand VI, which Charles III ordered removed in 1760.
