On the northern slope of the Rotenberg in the southern Harz foreland lies "König Heinrichs Vogelherd"
The early medieval castle complex above Pöhlde today consists of reconstructed remains of walls and dates back to the 9th century.
The castle was a frequent residence of the first German king, Henry I, who indulged in bird hunting here. According to legend, it was here in 919 that King Henry I received the news of his accession to the throne and the place was given its current name: "King Henry's Vogelherd".
