Jehay Castle, Protected heritage castle in Jehay, Belgium

Jehay Castle stands in a moat in Amay, its walls built of alternating light and dark stone squares. The main block has a steep dark roof with a small tower at its left corner and a taller pointed turret with a lantern top at its right; two round towers with conical roofs flank the facade, which is pierced by rows of small rectangular windows. A lower wing extends left, and an arched stone bridge links the right side to a gatehouse.

The seigneurie of Jehay is documented from the 12th century, but the present castle was built around 1550 for Jean Helman de Sart and his wife Marguerite del Falloise. Through Jeanne de Sart's marriage to Arnould de Merode it passed to that family until 1720, when Lambert van den Steen bought it; his descendants kept it for 280 years. Alphonse Balat renovated and extended it in the 19th century, and the Province of Liège acquired it in 1978.

The castle's name comes from the seigneurie de Jehay, whose lordship is documented from the 12th century; the estate stayed with the van den Steen family for 280 years. Count Guy van den Steen, its last private owner, redesigned the gardens in the mid-20th century, and 18th-century drawings by Liège artist Remacle Leloup record the earlier park.

The domain is open every day except Mondays, from April to October. The castle interior is closed for a long restoration campaign, so visits focus on the grounds and gardens. The site lies in Amay, Liège Province, and is reached by road from the surrounding villages.

The medieval predecessor of the castle is known only from some vaulted basements of its former keep, which date from the 13th century; the exact site of the earlier fortress has never been located. The present building was called a "beau neuff chasteau" in an archive document of 1580.
