A typical medieval walled town, Segovia is surrounded by formidable ramparts dating back to the 11th century. A substantial portion of the ancient limestone walls has been preserved, starting at the Alcázar fortress.
The ramparts feature characteristic crenellations, blind arches, towers, and entrance gates with horseshoe arches. Three of the old entrance gates remain: San Andrés gate, San Cebrián Gate, and Santiago Gate.
Inside the former guards' headquarters, tourists can take in an extensive view of the walls that defended the upper areas of the city. Tourists can also take a walk along the ramparts, overlooking the Jewish quarter and the city's monuments. Guided tours are available.
