Castle Widooie is a historic castle farm in Tongeren, Belgium, with origins tracing to the 9th century. The property forms a closed estate with four wings surrounding a rectangular courtyard, partly enclosed by a moat and surrounded by parkland. In 1559, it was granted as a fief, and across subsequent centuries, ownership passed through noble families including the Schaetzen. Today, the estate serves as an elegant event venue, having been transformed into an ecological park with carefully cultivated landscapes that complement its medieval architectural heritage.
