Walk along the city walls but be careful if you're walking on them, it is a steep fall!
Because of Toledo's location, surrounded by the river on three sides, the only possible way to attack Toledo would have to be from the north, which is where the highest and stoutest walls are.
The old city walls have around since the Roman times and some of the remaining walls that are still evident around the city come from this time. The walls were were reconstructed in 674AD by Wamba, the Visigoth King and finished by Alfonso IV.
The famous City walls of Toledo is a mish mash of various construction and designs for more than 1,800 years as it was initially on the roman settlement part and eventually expanded when the area became the capital of various forces such as the Visigoths, the Andalusian Arabs and finally the local Spanish headed by King Alfonso VI, who captured it from the Moors during the Reconquista. The City walls has various guard towers, ramparts and isolated sections of which is again due to the mish mash of styles and has different gates and entries such as the Puerta San martin, Puerta Alcantara, Puerta Alfonso V, Puerta Del Sol, Puerta CambronI and Puerta Bisagra.
