Historical minarets form a bridge between the past and the present as a symbol of cultural and architectural richness. For this reason, their protection against earthquakes and their transfer to future generations are of great importance. In this study, the improvement of earthquake responses of minarets was investigated. A liquid column damper that can be made without causing permanent damage to the structure was designed. Two main models, with and without liquid damper, are considered, and separate nonlinear dynamic analyses are conducted under the influence of three different ground motions. The liquid–minaret interaction is achieved using the coupled Eulerian–Lagrangian approach. Compared with the existing model, the model with a liquid damper showed effective reductions in relative displacements (U) of 33%, 16%, and 67%, and in stresses (Smax) of 39%, 44%, and 47% under the effects of the Dinar, Erzincan, and Elbistan earthquakes, respectively. Furthermore, it was observed that the damage ratios (dT = 0.95) in the structural elements after the earthquake in the existing model without liquid damper exceeded the limiting values. In the proposed model with liquid damper, the damage ratio was not exceeded in the Dinar and Erzincan earthquakes, while only 0.1% of the total elements were damaged in the Elbistan earthquake. Analysis shows that adding a column liquid damper to the minaret reduces the vibration and permanent deformation of the structure and therefore reduces earthquake damage to the structural elements.
