According to
dendrochronological research the wooden beams date back to the year 1202; the gate was first given documentary evidence in 1238 as
"Porta Sancti Martini" (Latin
Gate of the Holy Martin). Over the centuries it has been reconstructed several times. At one time, it also served as a prison and it was said of its occupants that they had donned "The Cloak of Martin". From the 17th century on the side of the gate facing the city was decorated with a picture of
Martin of Tours. During this time, due to the construction and leveling of the suburbs by
Sébastien Le Prestre de Vauban, the gate's link to the city was lost. Thus,
Salzstraße served as the main access road from Höllental. There have been numerous restorations of the picture, the most recent of which was in 1851 by Wilhelm Dürr. In 1968/69 the picture was removed. To date the local town council has still not been able to decide on a new image. As a result there remains a blank spot in honour of the conflicts between the Freiburg Civil Defence and the French Revolutionary Forces. The Martinstor underwent its biggest change in 1901. By this point, the surrounding buildings surmounted the old city gate and the old passageway had become too small for the growing city and the new tram infrastructure. Having momentarily considered demolition, the city council opted instead to modify the building. Under the direction of Carl Schäfer the tower was heightened from 22 to 60 metres and a new roof construction in the architectural style of the 15th century was added. An additional gate with a larger thoroughfare, designed in the same architectural style, was erected next to the original gate. A German
Reichsadler was painted on the outer facade of the gate above the emblems of Freiburg and of the nearby region of
Baden, before it was removed in 1951. A replication of a baroque sandstone plate depicting the
Double-headed eagle of the
Holy Roman Empire was later installed. == Present ==
