CE Jordán casemate, Military fortress in Malá Víska, Czech Republic.

The CE Jordán casemate is a one-sided infantry bunker on the northern slope of Houpák hill at 760 m, on the Jordán impact area in the Brdy highlands. Its 200 cm ceiling and 225 cm front wall, covered with stone and earth, were built to the second degree of resistance; the upper floor held the machine-gun and anti-tank gun room, the lower floor the 22-man crew quarters.

The bunker was built in 1936 by the Prague firm Litická a.s., with rough construction running from 14 April to 27 May 1936 at a cost of 884,000 Kč. It served as a test and training object for heavy fortification weapons and equipment, and in August 2012 it was declared a cultural monument. Since 2017 it has been managed by the Military History Institute Prague.

The structure shows how Czechoslovakia wanted to protect its borders and what building techniques were possible at the time. You can still see the solid construction that was designed to train soldiers.

The casemate lies on the Jordán impact area on the northern slope of Houpák at 760 m, on the boundary between Obecnice and Malá Víska. It is reached on foot along marked trails through the Brdy forest; the terrain is steep and the interior unlit, so bring sturdy shoes and a torch.

The facility served not only for training soldiers but also for testing and refining new fortification techniques. This makes it an important location for military innovation during that era.
