An unfinished outlying fort

Fort X Henrysin is part of the outer ring of forts of the Modlin Fortress and was never completed. This connects a local point of reference—the individual fort in Henrysin—with its place in a larger fortress system. Its unfinished status describes the structure, while the outer ring identifies its position within the fortress. These details answer different questions: What is Fort X itself, and how does it fit into the Modlin Fortress? For travellers considering Henrysin for its cultural history, this distinction makes the historical focus more specific than simply naming the fortress.

The GIU observation cupola

One distinctive surviving detail is the armoured observation cupola of the GIU model. It is located on the ceiling of the underground complex, was manufactured in 1913, is well preserved and is described as unique. The year refers to the manufacture of the cupola, not to the completion of the fort. This distinguishes the specific date associated with this structure from the unfinished fort as a whole. The model, its location within the structure, its condition and its year of manufacture provide a more precise context for the cupola than a general description of the complex.

Film history in the underground rooms

The underground rooms offer another perspective: footage for the television series “Tajemnica Twierdzy Szyfrów” was filmed there. This connection adds a specific film production to the architectural history. The cupola and the filming represent different aspects of Fort X: one is a surviving structure, the other the use of the rooms as a filming location. Together, they give the site’s historical focus more definition without conflating the two stories.

The fortress road to the fort

An original cobbled fortress road leads to the fort. It is a protected monument. This means that the road to the fort is another distinct protected feature, in addition to a structural element of the underground complex being among Fort X’s specific historical features. This distinction helps ensure the road is not treated merely as a route: it is part of Henrysin’s historical context. Unlike the cupola, which is located on the ceiling of the underground complex, the road points to the approach to the fort.

Location and visit planning

There are two approximate reference points to help orient you. Fort X lies about 2 km north of the Vistula and about 3.5 km west of Fort I in Zakroczym. One detail locates the fort in relation to the river, the other in relation to a named fort in Zakroczym. Together, they offer two different ways to establish its location.

When planning a visit, take the access situation into account. Fort X is privately owned and in continuous use; access is unavailable or severely restricted. Check whether a visit is possible before you go. If you are looking for a holiday apartment in Henrysin, the fort can serve as a cultural point of reference when choosing where to stay. Independently of that, check in advance whether a visit may be possible.
