In 1306, a church or chapel dedicated to St. Nicholas in Aremberg was mentioned for the first time. A pretty jewel awaits the visitors of the church today.
The Dreimühlen waterfall is probably the most interesting waterfall in the Eifel. It was formed from limestone deposits of three spring tributaries of the Ahbach. Due to the constant deposition, the sinter bank is constantly "growing", which is where the name "growing waterfall" comes from.
