The Breisach Gate

On Monday, Freiburg's archaeologist, Dr. Bertram Jenisch, talked in this year's lecture series "In the Year and on the Day" about the Breisach Gate.

 
As Lagniappe he reported about new traces of Vauban's legacy his institute had recently uncovered when digging into the Bastion St. Louis on which the Colombischlössle is built.

In an earlier blog, I wrote:

When firearms dominated warfare, Freiburg's old city wall became a joke. During the Thirty Years' War and, particularly during the aggressive French wars in the late 16th and early 18th centuries, artillery quickly opened breaches in the fortifications (Bresche schießen) several times.

When Freiburg became a French city in 1677, Sébastien Le Prestre de Vauban started surrounding the city with modern fortifications, thus integrating Freiburg into France's northern fortification belt. Contemporaries called his work, “La dernière folie de Louis XIV."

The Breisach Gate is the white square within the fortification.

Gate openings were undersized, allowing the passage of just one horse-drawn carriage. This is clearly visible at Neuf Brisach, Vauban's masterpiece.

The situation around the Breisach Gate from a bird's eye view in the 19th century. Today's Holzmarkt (wood market) was the Viehmarkt (cattle market), the former Kaiser Straße has become Kaiser-Joseph-Straße, and the road Dauphine Straße built for the visit of Marie-Antoinette to Freiburg in 1770 has made way to Federal Road 31 into the Black Forest.

Towards the end of the 19th century, the building was raised by one story, and two side wings were added. It served as a school at the time.

Today, the interior and forecourt of the Breisach Gate are used for gastronomic purposes.

Dr. Jenish presented a slide showing the various sites in Freiburg where he and his team had been active in recent years.

The Bastion St. Louis - a small red dot marked "b" on the above plan - was recently dug up as part of the redesign of Colombipark.

In addition to many objects from the time when the bastion was built, the most spectacular find was an inclined tunnel that led from the surface to the fortress's apron. It was probably used for reconnaissance purposes during a siege. 

Dr. Jenisch's lectures are always good for a surprise.
