Plaza Mayor of Madrid
La Plaza Mayor (Main square, in english) is an arcaded rectangular plaza, 129 meters long by 94 meters wide, which is completely enclosed by tall residential buildings.
The origins of the Plaza Mayor date back to the fifteenth century, when at the confluence of the paths of Toledo and Atocha, a market was held on the site. In 1580, Philip II commissioned a project to remodel the plaza, which would not be completed until 1619, during the reign of Philip III.
The Arc of Cuchilleros is the most famous of the nine gateways in Madrid's Plaza Mayor and is located in the southwest corner of the square.
Among the establishments in the plaza, the Sobrino de Botín restaurant is the most famous, it appears in the Guinness Book of Records as the oldest restaurant in the world, founded in 1725.
