Horseshoe shape

It is also common in Visigothic and Islamic architecture as an arch shape.

If the windows are not designed to provide light, they serve as a decorative element.

Since ancient times, there have been various functions attributed to a horseshoe shape.

The stage at Opéra Garnier in Paris or the auditorium at Musiktheater im Revier in Gelsenkirchen-Schalke, for example, are designed in this form.

In addition, there are settlements whose concept is based on this form, for which the Berlin Hufeisensiedlung or Kirchmöser-Ost housing estate can be mentioned.
