Antequera Town Hall Tourism Department. The present Plaza Coso Viejo (Old Arena Square) was previously known as the Vegetable Square, as the open market was placed in there. The square has recently been restored and now there is, just in the middle, a horse sculpture depicting the Infante Don Fernando; at the end, there is a fountain showing the four elements: water, fire, air and earth. From the high town, the Mirador de las Almenillas (The small Battlements Viewpoint), the city walls and the Arco de los Gigantes (The Giants’ Arch) come into sight. In the square, there are two significant buildings: the Palace of Nájera and the Convent of Saint Catalina de Siena.
