The cellar of the abbot’s house of the Abbey of Dieleghem or the ‘game of seven errors’. How building archaeology reveals the history of a difficult building site.

The cellars of the former abbot’s house of the abbey of Dieleghem, Jette, reveal the background to the construction and organisation of a prestigious building from the end of the 18th century. The construction of the building took place over a period of more than 20 years, between 1783 and 1794-1795. The archaeological analysis of the masonry preserved in the cellar shows anomalies and changes in the programme, in other words, “errors” that make it possible to understand a difficult construction site and a schedule under pressure. These ‘mistakes’, which the public is invited to discover during the visit, reveal more than just the details of the great history of a Brabant abbey at the end of the 18th century.
