Ponttor
Description
The Ponttor in Aachen, Germany, (known in the 17th and 18th centuries as the Brückenpforte or Brückenthor) is one of the two remaining gates of the original city wall of Aachen (the other being the Marschiertor). The westernmost of the north-facing gates (the other being the Sandkaultor, which no longer exists), the Ponttor was built in the 14th century and manned by soldiers and militia throughout the Free Imperial City of Aachen era. Today, the Ponttor is used by German Youth and Scout groups belonging to the German Scount Club (1945) and the German Scout Association Saint George.StructureThe Ponttor was constructed as a right-angled three-stock tower castle. In the main entrance, there is a Portcullis as well as a machicolation, through which things could be dropped on invading forces. A bridge passage with crenelations spanned a moat and was strengthened in the foregate with two reinforced towers (barbicans). The building material was Devonian sandstone, Pennsylvanian carbonite sandstone and quartzite, with the framing material made of light bluestone.
