All Saints' Abbey, also known as Kloster Allerheiligen, is a former Cistercian monastery located in the Black Forest region of Germany. The abbey was founded in the 12th century, and throughout its history, it was a place of spiritual and cultural importance.

The abbey is surrounded by natural beauty, including forests, rivers, and waterfalls. Its church is considered one of the most impressive examples of Gothic architecture in the region, with impressive stained glass windows and intricate stonework.

Over the centuries, the abbey underwent several expansions and renovations, with the most significant work being carried out in the 18th century. During the Napoleonic Wars, the abbey was dissolved and its buildings were used for secular purposes. In the 19th century, the abbey was rebuilt as a tourist attraction and became a popular destination for nature lovers and hikers.
