A group of four forts and associated batteries occupy this portion of high ground to the north of Paris offering protection to route ways from the north east and northwest and of course standing on the line of approach from the north. Two further forts occupy detached hills to the south east of the main block towards the valley of the La Croud River. A 'route strategique is marked on the map running east from the Fort de Domont. Clearly the three main works of Domont, Montlignon and Montmorency were sited to offer close mutual support on what must have been seen as a crucial sector of the defences


The Fort De Domont is the most northerly of these works. Pentagonal in shape it is defended by a ditch protected by a double caponier on the north angle and two caponiers on the 'shoulders'. The fort is currently run as a training centre for the French fire service - the much loved and respected Sapeurs-Pompiers. Curiously, despite the fact that a training exercise was underway a casual approach was rewarded with permission to look around sections of the fort providing we avoided the fires and some of the tunnels where there were 'big holes' - my translation. As ever additional information is published with many photographs by the Index de Fortification Francaise. An outline local account of the fort's history is on line as are photos and drawings of the armoured cupolas installed on the site.
