Bastion (toreta) Gradenigo se nalazi na uglu zapadnog i sjevernog pravca bedema. Nastao je 1498. obziđivanjem srednjovjekovne kule na mletački način – dodavanjem kordon vijenaca i vrlo blage eskarpe. U parapetnom zidu na vrhu bastiona nalaze se toparnice i puškarnice, raspoređene između četiri lučna otvora. Platforma za topove izvedena je preko jačeg romaničkog svoda sa bočnim sferičnim nišama za đulad u prizemlju bastiona. Na centralnom dijelu, iznad grba sa krilatim lavom, locirana je stražara sa puškarnicom.
Bastion Gradenigo
The bastion (turret) Gradenigo is located at the corner of the western and northern directions of the town walls. It was built in 1498 by walling up a medieval tower in the Venetian style by adding cordon wreaths and a very slight escarpment. In the parapet wall on the top of the bastion are located gunnery and loopholes, arranged between four arched openings. The platform for the cannons is built over a stronger Romanesque vault with lateral spherical niches for the doulas on the ground of the bastion. In the central part, a guard with a loophole is located above the coat of arms with a winged lion.
