Castrum Cirpi is one of the most evocative Roman military sites along the Danube frontier — an ancient fort whose outline is still clearly readable in the landscape beside the Szentendre branch of the Danube. If you love places where layers of history are quietly waiting beneath your feet, this is unmissable.

The fort sits in the Váradok-dűlő area on the outskirts of Dunabogdány, on the left bank of the Szent János stream, right next to the Danube. The gentle hills of the Danube Bend surround the site, and the scenery shifts beautifully through the seasons — fresh green meadows in spring, a lush and peaceful atmosphere in summer, and a golden, reflective mood in autumn. This is not a site of towering reconstructed walls; instead it offers something rarer — a tangible, undisturbed connection with the past in a tranquil riverside setting.

• Dunabogdány (roadside parking near the Tahitótfalu road) — easy walk along the Danube bank to the Váradok-dűlő area, flat terrain, approximately 15–20 minutes on foot.

• The outline of the fort is still visible in the landscape as subtle ridges and depressions — a historical map is a helpful companion.
• A Silvanus altar stone from this site is on display at Solomon's Tower in Visegrád.
• The first archaeological excavation was carried out by Ákos Szalay in 1930; no systematic dig has taken place here since.

A fascinating footnote: the medieval village of Várad once stood on the very site of the Roman fort, and was destroyed by the Ottomans around 1566 — which is why the area still carries the name Váradok-dűlő today. Together with a paired fortlet at Verőce on the opposite bank, Castrum Cirpi once formed a key river-crossing control point on Pannonia's eastern frontier.
