Brownsea Island is the largest of the islands in Poole Harbour and its history dates back to the Iron Age, with evidence of early human settlement.

In the 16th century, King Henry VIII built a fort on the island to defend against potential invasions.

During the 19th century, the island was privately owned and used for various purposes, including agriculture and pottery production.

In 1907, Lord Baden-Powell held the first experimental Scout camp on Brownsea Island, marking the birth of the Scouting movement.

The island was acquired by the National Trust in 1962 and is now open to the public.

Today, Brownsea Island is a popular tourist destination, known for its diverse wildlife, including red squirrels and rare bird species.

It continues to be a significant site for Scouting and Guiding, hosting events and commemorations related to the movement's origins.
