The Puerta de Bisagra (originally Bab al-Saqra, also called 'Puerta de Alfonso VI') is a city gate of Toledo, Spain, built in the 10th century, in the time of the taifa of Toledo. It is also called 'Bisagra Antigua' to distinguish it from the Puerta de Bisagra Nueva which was built in 1559. The gate was the main entrance to the city and dates from the Andalusian period.
