'Bourmicht' is a field name in Bertrange.
In Luxembourgish it is 'Buermiicht'. An intercommunal business zone was created on this land next to the motorway at Helfent. The foundations of a Gallo-Roman palace villa here have been known since 1847; the land register calls the spot 'Rothen Zillen', red bricks or tiles. What 'Bourmicht' means, we have not yet found out.
