Landau Gate

The Porte de Landau (1708), a witness to the Vauban era, is built on medieval fortifications. A sun sculpted on one side of the door recalls the oath of allegiance sworn to the King of France in 1680. Upstairs (accessible only during guided tours) in the exhibition room is a model of the fortifications of the city, according to the plans of 1782.
On July 24, 1870, a patrol of Baden dragoons, commanded by Baron Zeppelin, entered France through this gate; this incursion constitutes the first warlike act of 1870.
The association "Action 1870" of Woerth organized, on July 24-25 and 26, 2021, a traveling historical reconstruction in memory of the recognition made, in 1870, by Count Ferdinand von Zeppelin. A group of 4 Bavarian riders in period uniforms took part.

The Landauer Tor was built as a fortress tower in the middle of the 13th century together with the other fortress structures in the city and served as a subtower to defend the eastern entrance to the city. A room for the tower watchman was set up as early as 1615. The actual tower was demolished in 1706 along with most of the other city towers; the current building was built on its base as a city guard's apartment. To the east, the former coat of arms of France once adorned the building, which was replaced in 1792 by a figure of the sun, the heraldic symbol of Louis XIV, and of which fragments have still been preserved. From 1978 to 1985 the building was renovated.

The gate was part of the "Lauterlinien" built under Marshal Vauban in 1708. It was built on an older foundation. In the gable on the north side you can see a sun that is reminiscent of the sun king Louis XIV.
In the upper part of the building (only accessible during guided tours) there is a model of the city's fortifications, based on the plans from 1782.
