10.5cm Casemate


10.5cm Jager Casemate

Front of casemate

This casemate is one of 21 'Fortress' bunkers built in Guernsey to house 10.5cm K331(f) guns. Four were installed here at Fort Hommet. Construction work was carried out by the O.T. commencing April 1943 by which time the railway from St. Peter Port had reached Vazon.  This site was surveyed and acquired for restoration by the Occupation Museum, internally if was found to be dry and structurally sound but stripped of every fitting. Excavation of the entrance started in April 1993. By the beginning of 1994 the gun had been replaced, doors re-hung and the ceiling and walls repainted. The rest of the year was devoted to replacing all the internal fittings back to how it appeared in 1943. The casemate finally opened to the public on 6th May 1995. The gun is a French manufactured Schnieder field gun made at the Le Creusot works in 1916. After the fall of France in 1940 a large stock of these guns and ammunition fell into German hands. As they were surplus to the needs of the Field Artillery, many were stripped from there wheeled carriages and converted for mounting in these casemate positions.

Crew Room

The casemate would have been manned by a crew of four or five men and one NCO and when off duty would have used this crew standby room. Nine bunks are provided to allow for extra crew under prolonged action. The air ventilation pump and heating stove is in this room. Open in the summer 2-5pm Saturdays

M19 Bunker

Opened in March 2010, this Type 633 bunker for the M19 Automatic Mortar has been cleared out and subject to minor conservation works. Bulk head lighting is being installed and while most of the rooms will remain as found, the turret area and ammunition room will be restored.

Excavations at the 4 other Type 633 bunkers over the last couple of years has produced a wealth of important parts, with enough to reassemble two thirds, from the floor jack and lower deck up to the rotating top deck. These parts are currently undergoing extensive restoration.

The destroyed turret area will be subject to extensive reconstruction work, with an internal steel skin being fitted to replicate the turret interior. The area of missing concrete will then be in-filled and the roof slab made good. This will hopefully cure the many areas of water ingress through the mass of cracks radiating out from the turret area.
