Although older in time, the gate was named after the Sahat Tower. The original gate was built in the medieval rampart, and a part of its vault built of thin bricks has been preserved to this day and can be seen inside the gate. It was made immediately after the Austrian conquest of the city in 1688, and it got its final shape a few years later, during the reconstruction of the rampart, probably according to the design of Andrea Cornaro. The gate was built in the form of a vaulted passage through the rampart, with two rooms on the side and three decorative niches marking the entry into two more side rooms intended for guard accommodation. They have been walled up and filled with earthen embankments since the end of the 17th century.

During extensive archaeological excavations conducted in the summer of 2004, the remains of Roman log cabins, as well as a house from the late Neolithic and Copper Age, were also discovered at this site.
