MO-S 18 V oboře casemate, Infantry casemate in Šilheřovice, Czech Republic.

MO-S 18 V is a reinforced infantry casemate constructed from concrete with a reconstructed steel dome at an isolated location near Šilheřovice. The fortification represents the standard design of Czechoslovak border defenses from this period and is accessed via an educational pathway.

Built between 1936 and 1938 by the Prague firm Václav Nekvasil as part of the Hlučín sector (ŽSV II), the casemate was a heavy one-sided infantry blockhouse fitted with a steel dome. German troops tore out the original dome in 1939, but the embrasures survived; a new dome was installed in 1991 when the fortification museum was established.

The casemate is part of the Czechoslovak Fortification Museum in Darkovičky and stands on the route of the Darkovičky educational trail. A memorial plaque inside recalls Jaroslav Švarc, who served here in 1938 and took part in the 1942 assassination of Reinhard Heydrich.

The casemate lies on a walking route that connects to the Czechoslovak Fortification Museum in Darkovicky, allowing it to be easily combined with a broader visit. The pathway is generally accessible on foot but requires sturdy footwear and careful attention to the ground conditions.

The original steel dome was torn out by German soldiers in 1939, but the embrasures remain original, a rarity since most casemates were looted for scrap. A new dome was installed in 1991 when the museum was established.
