Wiesenbatterie Schillig, Protected area in Wangerland, Germany.

Wiesenbatterie Schillig is a nature reserve covering about 6.6 hectares in Wangerland. The site is defined by a forested section, which stands out as unusual among the treeless marsh landscapes typical of the Lower Saxony region.

The site was constructed as a military fortification before World War I. After World War II in 1945, it was heavily damaged by explosives and later converted into a protected nature reserve.

The name comes from an old military battery that once stood here. Today visitors walk through the reserve to observe the woodland and natural surroundings that make it different from the flat marshes around it.

The area is best explored on foot, with accessible paths through the wooded section and across the open marshland. Visitors should wear weather-appropriate clothing since the air is often damp and conditions can change quickly.

The site was built as a defensive position before World War I and was largely blown up in 1945 after World War II; the trees that grew over the rubble now form the wooded patch that gives the reserve its value for birds. It has been protected since 7 August 1982 and lies entirely within the EU bird sanctuary "Wangerland".
