Reichenau Island, a UNESCO World Heritage Site, is renowned for its historical monastic complex that dates back to the 8th century. Founded by the monk Pirmin, the island became a significant cultural, religious, and artistic hub in the region, influencing medieval monastic architecture across Europe. The island's three churches, adorned with medieval wall paintings, are a testament to its rich artistic heritage. Connected to the mainland by a causeway, Reichenau continues to be a place of historical fascination and beauty.
