Between 1887 and 1915, in the area of today’s Janówek Pierwszy, Janówek Drugi, and Trzciany, Tsarist sappers built a system of permanent and field fortifications—the Janówek Fortress Group. It formed part of the outer defensive ring of the Novogeorgievsk (Modlin) Fortress. The Strongpoint No. 10 fortification complex served as the southern wing of the Janówek Fortress Group. This complex included Strongpoint No. 10 (a concrete barracks shelter reinforced with field fortifications) as well as two 4-gun batteries of heavy artillery with field shelters for their crews.
In 1915, during World War I, Strongpoint No. 10 was manned by soldiers of the 19th Company of Novogeorgievsk Fortress Artillery, while their rear base in Boża Wola housed the staff and a detachment of the 626th Tambov Militia Unit. The heaviest fighting for the Modlin Fortress in August 1915 took place in the Pomiechówek sector. The Janówek Fortress Group was besieged by the German 169th Landwehr Brigade. Upon hearing of the surrender of the Novogeorgievsk Fortress, Russian soldiers blew up almost all of the permanent fortifications. Their picturesque ruins have survived to this day. Relatively well-preserved remains of the field fortifications can also still be admired.
