Sashes Island

Sashes Island is a river island in Cookham situated between two channels of the Thames and connected to the mainland by footbridges. The island was divided into sections when a canal ditch was constructed, with much of it covered by excavation material from that work.

The island served as a defensive position during Anglo-Saxon times to protect against Viking attacks. Excavations in the 1800s uncovered iron weapons from the early Viking period, revealing its military importance during medieval conflicts.

Archaeological excavations in 1856 and 1860 revealed iron weapons from the Viking period, providing evidence of the island's military significance during early medieval conflicts.

The best way to reach the island is on foot using the existing paths and bridges from the village. The ground can be damp in places and uneven, so sturdy footwear is advisable.

Medieval structures likely remain buried beneath the island's surface layers, hidden by centuries of deposits. The land has remained relatively stable since prehistoric times, preserving these hidden remains.
