Wormser Tor, Triumphal arch city gate in Frankenthal, Germany.

The Wormser Tor is a stone gate structure featuring double pilasters, a wide gable, and a cross-vaulted passage running through its center. The structure served as a main entrance to the fortified city and remains a distinctive landmark in the urban landscape.

Built in 1770–72 under Elector Karl Theodor, the Wormser Tor was one of two representational gates rather than a defensive work. The city walls were largely demolished by 1870; in 1879 a council vote to remove the gate was overturned by a citizens' referendum, after which 16 councillors resigned and only the adjoining buildings were torn down. Damaged in World War II, the gate was preserved and later restored.

The gate displays decorative carved reliefs and portraits of Elector Karl Theodor, reflecting artistic tastes from the late 1700s. These ornaments show how important this passage was to the city's identity.

The gate marks the northern entrance to Frankenthal's pedestrian zone and city centre, at 95 m above sea level. Since the buildings beside it were demolished after the 1879 citizens' vote, it can be walked around on both sides, so pedestrians and cyclists pass beside the arch rather than through it.

In 1879 the town council voted to demolish the gate for a better entrance to the centre, but a citizens' referendum rejected the plan and 16 councillors resigned. Only the buildings beside the gate were torn down, so it could henceforth be bypassed on both sides. A fixed illumination was installed on the gate in 2007.
