This square is surrounded by different buildings, each one from a different era, style, architecture, and more. One of them is City Hall, that was slowly built through 1644-1787. Next to that is the La Casa de Cisneros, a look-alike palace. This house, carrying the name of Archbishop Cisneros that lived in the area between 1436-1517, was built in 1573. It is considered an excellent example of S panish Renaissance architecture. When City Hall filled up at the start of the 20th century, the Casa de Cisneros was purchased by the city municipality.
Be sure to also see the Torre de los Lujanes, a beautiful building in the square. It was built in the Mudéjar architecture style, a traditional Islamic style that was preserved in Spain, even with the Christian rule. Throughout history, that tower became famous, for it was the place where the French Emporer Francis I was imprisoned after he was defeated by Carlos I in the battle of Pavia.
Notice the National Archives (Nacional Hemeroteca) for journalists, a design that was also influenced by the Mudéjar style of architecture.
At the center of the square is a bronze statue of Alvaro de Bazan, considered to be the Spanish hero of the Lapanto War. This war was a naval war that happened in 1571 near the beaches of Greece, where the naval coalition of forces of the Pope, called the Holy League, beat the Ottoman navy. The winning coalition was made from the Hapsburg House of Austria, Venetians, and the Spanish. The winning battle meant that the Austrian Hapsburg House was to have control over the Mediterranean Sea.
