Pillbox No. 401 is a long-term defensive point (DOT) that is part of the first line of defence of the Kyiv Fortified Area. Pillbox No. 401 is located on the northern outskirts of Bilohorodka. It is a monument of history, science and technology of local significance.
Pillbox No. 401 is a so-called “mine group”, consisting of two single-embrasure casemates and one 2-storey machine-gun semi-caponier with two embrasures, which were connected by underground galleries (poternas) about 485 metres long; the armament consisted only of machine guns. It is a unique fortification built to an individual design, but it was never fully fitted out for full operation.
Organisationally, Pillbox No. 401 was part of the 3rd Battalion Defence Area of the KyUR (Kyiv Fortified Area).
In 2006 the film “Shtolnia” (The Adit) was shot in the poternas of Pillbox No. 401.
The pillbox has the status of a monument of history, science and technology of local significance (order of the Ministry of Culture of Ukraine of 03.02.2010 No. 58/0/16-10 as amended on 16.06.2011 No. 453/0/16-11, protection number 513/32-Ko).
