The Château d'Ingwiller was a castle located at Ingwiller, approximately 30 km (19 mi) west of Haguenau in Bas-Rhin, in the Alsace region of France.

Extensively renovated several times, its purpose was more residential than military and in the end it did not survive the turbulent history of Alsace.

The count died at the castle on 5 January 1480, predeceasing his own son, Philippe, by just five days, triggering a period of funerals and some uncertainty.

During the seventeenth century the castle enclosure contained, along with the usual basics, an arsenal, an abattoir, a laundry, a bakery, stables, a barn and a shed.

The bays of the synagogue are semi-circular and twin-shaped and the front of the Torah is made of paired sandstone.\The tables of the Law are in relief on the south façade.

However, the community dwindled sharply over the next decades and the building fell into disuse and suffered damage from water infiltration and neglect.
