Cairo "City of thousand minarets" holds a huge number of historical minarets that suffered from deterioration and different levels of damage during past earthquakes that make them more vulnerable to seismic actions, besides bad restoration, lack of maintenance. Preserving and protecting historical minarets against earthquakes is very important. In this work, the seismic vulnerability of a historical minaret in Cairo, the eastern minaret of Sultan Hasan Mosque, evaluates by the empirical method based on a new vulnerability assessment method that was published in 2018 for slender masonry structures. Moreover, experimental evaluation is applied using ambient noise vibration criteria that are recorded at different levels of the minaret. In addition to proposing some intervention aspects for the minaret's restoration based on the outputs of the two applied methods
