The story that haunts this land

Your journey begins at Valkhof Park, a Dutch national monument classified in 1969. Here, on the site of a Carolingian palace built by Charlemagne around 777, you search the 1st and 2nd-century Roman ruins, remnants of the legionary camp of Noviomagus, capital of the Batavians. Emperor Henry II had the Saint Nicholas Chapel built here in 1030, whose remains you examine. Every stone in this Nijmegen park, overlooking the Waal from the Kops Plateau, reminds you of Nijmegen's long history, from Drusus's fortifications to medieval emperors. This route is an immersion into a potential UNESCO Roman heritage site.

A short walk away, Museum Het Valkhof, opened in 1999, welcomes you to its 2500 m² space. It is here that the Roman treasure of Nijmegen, consisting of 18 silver statuettes from the 2nd century, awaits your examination. You also discover the reconstructed remains of the Roman forum of Noviomagus, capital of the Batavians. The collection of Byzantine icons from the 11th-16th centuries, including a Virgin Hodegetria icon dating from around 1200, offers a striking contrast with antiquity, highlighting the cultural richness of Nijmegen and Gelderland.

Your investigation then leads you to the Stevenskerk, a Gothic church built between 1316 and 1550 from Ubbergen sandstone. Its 75-meter high tower and bells dating from 1498-1657 resonate with the history of Nijmegen's old town. Used as a parish church until 1965, it has been a concert hall since 1974. The historic organ from 1618, restored in 1982, offers you an acoustic break before continuing your GPS scavenger hunt, revealing the secrets of this Dutch national monument.

The Grote Markt, a central square since the 13th century, was the heart of medieval commerce in Nijmegen. The neo-Gothic town hall from 1554, with its 56-meter tower, dominates the square. You observe the statue of Mariken van Nieumeghen (1922), a 16th-century literary character, and imagine the weekly markets held there since 1205, following the market charter granted by Otto II. This site in Nijmegen's history is a must-see to understand the urban development and heritage of Gelderland, before entering Lange Hezelstraat, the city's oldest street, paved since the 13th century and lined with over 200 historic monuments from the 16th-18th centuries. This ancient pilgrimage route to Santiago de Compostela testifies to medieval exchanges.

Your exploration culminates at the Mariënburgkapel, a Gothic chapel built between 1481 and 1509 with its rib vaults. 33 m long and 15 m high under the vault, it houses 16th-century frescoes depicting the Virgin and Child. Having served as a warehouse during World War II before being restored in 1953, it embodies Nijmegen's resilience. This thematic circuit of Gelderland will have offered you an interactive visit, leaving you with the satisfaction of having deciphered a part of Nijmegen's history, from Roman legions to medieval pilgrimages, and of having discovered a unique heritage in augmented reality. You leave with a deep understanding of the city, its monuments, and its central role in Dutch heritage.
