Torenmuseum Valkenburg

Valkenburg, located in South Holland, gained international archaeological fame through numerous excavations, particularly focusing on the Roman castellum, Pretorium Agrippinae, which stood here two thousand years ago. The Torenmuseum houses a permanent exhibition dedicated to Roman history, showcasing parts of armor, tools, and equipment that were excavated on-site.

The Castellumplein, where the Torenmuseum is located, resembles a mound. This mound was formed as a result of the successive presence of seven (!) castella at this site. Around the square, the outlines of the castellum have been made visible through round bronze markers embedded in the pavement.


Peutinger Map

"Do you want to know what our area looked like during Roman times? At the Katwijks Museum, you can view a map from Roman times, the Peutinger Map. The map is named after the monk Konrad Peutinger, who made copies of an original Roman map from the time of Emperor Augustus (27 BC - 14 AD)."
