Château de Triquerville

Château de Triquerville stands in the hamlet of Triquerville, now part of the commune of Port-Jérôme-sur-Seine in the Seine-Maritime department of Normandy. Tucked among farmland and tree-lined lanes in the Caux countryside, the seventeenth-century manor sits a short drive from the Seine valley near Lillebonne.

Who built the château and when?

Records trace ownership of the Triquerville estate back to the 13th century, when the land belonged to the Sorenc family. By the 16th century it had passed to the Craquesne family. The decisive change came in 1634, when the property was acquired by Pierre II de Mesnil Costé, a counselor at the Parlement of Normandy, the province's highest court. He commissioned the residence that still stands today, built in the sober brick-and-stone style associated with the reign of Louis XIII.

What does the château look like today?

The estate's centerpiece is a Louis XIII-style pavilion: a compact, symmetrical block topped by a steep roof, typical of Norman manor houses from the first half of the 1600s. Beside it stands a cylindrical dovecote, a feature that once signaled the owner's feudal privilege — only lords with full seigneurial rights were permitted to keep such a structure. The facades and roofs of the pavilion, together with the dovecote, were listed as a protected historic monument by a decree issued on 29 October 1968, recognizing their architectural and historical value.

Can visitors go inside?

The château remains a private residence and is still in use; regional records also associate the property with horse breeding, describing it alongside an attached stud farm. In practice this means the interior and grounds are not open to the public on a regular basis. Passers-by can, however, view the pavilion and dovecote from the surrounding road, a view that is especially striking in spring and summer when the surrounding greenery is at its fullest.

How do you get to Triquerville?

Triquerville lies within Port-Jérôme-sur-Seine, a commune created from the merger of several villages between Lillebonne and the Seine valley. A car is the most practical way to reach it, since the area is spread across a rural landscape of narrow departmental roads connecting the former villages. The nearest sizeable town is Lillebonne, known for its Roman amphitheater, making it easy to combine a stop here with another historic site in the same trip.

When is the best time to visit?

Since the château is mainly seen from outside its gates, late spring through early autumn is the best window, when the trees around the estate are in full leaf and late-afternoon light brings out the texture of the brick and stone facades. Winter visits can be limited by mist, which is common in this part of the Seine valley.
