Building 106, WWI Sentry Post, Chattenden Ordnance Depot

The building known as Building 106 is a reinforced concrete sentry post constructed to protect the Chattenden Magazine Enclosure W gate and the Lutnor Rail Junction. It is located on the east side of Lochat Road, which runs north-south from the magazine enclosure. The sentry post is approximately 2.5 meters high and has a polygonal shape with eleven sides and a shallow domed roof. The walls are about 30 centimeters thick and built in sections of approximately 60 centimeters. The roof is made using a corrugated former. Access is provided through a small, heavy hatched west door made of reinforced concrete, featuring a steel bar handle and external hinges. There are five observation apertures on alternate sides, each with an external horizontal splay approximately 70 centimeters wide, which could also function as small arms embrasures for handguns. The interior retains some metal sheet lining.
