The Mainz Wine Gate was renovated as the fourth city gate of the former Rhine fortification and handed over to the public during a small ceremony on site. Mayor Jens Beutel, Head of the Department of Monuments Norbert Schüler, and Erika Friderichs honored the donors present, Stefan Schmitz and his co-partners at G.L. Kayer Immobilien GmbH. It is the second gate in a row that has been repaired thanks to a generous donation from the Schmitz family and additional funds from the state capital of Mainz.

As a result of river straightening in the 19th century, today's Lauteren district was created in front of the city wall on the Rhine. Between 1873 and 1879, the "Rheinkehl fortification" was built with iron fencing and sandstone gates to secure the new riverbank area for military purposes. The Weintor gate was erected as an extension of Weintorstraße, with a vehicle passage in the middle and pedestrian openings on both sides, flanked by embrasures. On the initiative of the Mainz Monument Network/German Foundation for Monument Protection, the Weintor underwent extensive restoration in 2009.
In addition to a generous individual donation, other residents of the riverbank also contributed to the success of the renovation. New lighting shows the Rheintor in its best light in the evening.
