The Legend With Toledo almost undefended, the Almoravids besieged the city. Berenguela, only 23 years old, climbed the wall at what is now the Queen's Tower to verbally confront the Muslim leaders. According to tradition, her stern rebuke caused the besiegers to withdraw in shame.

The Queen's Towers are a monumental section of Toledo's medieval city wall, located on Calle Carrera, between the Bisagra Gate and the Almofala Tower. They form part of the old urban defensive system. This section of the wall is visible from outside the Bisagra Gate, extending eastward. The name "Queen's Towers" comes from Berenguela of Barcelona, wife of Alfonso VII, who defended Toledo in 1139 while the king besieged the Muslim fortress of Oreja (near Aranjuez).

The Alcántara Bridge is one of Toledo's most important historical gateways and a key engineering feat dating back to Roman times. Originally built by the Romans as part of the roads crossing the Tagus River towards the city of Toletum, it was rebuilt in several stages due to damage and flooding of the Tagus. Notable phases include: 10th century: renovation under Islamic rule (the horseshoe arch was added). 13th century: reconstruction under Alfonso X, from which the western tower originates. 1721: replacement of the eastern tower with a Baroque triumphal arch. One of the Alcántara Bridge's greatest attractions is that it offers one of the best panoramic views of the Alcázar of Toledo, thanks to its low position next to the Tagus River.
