The strategic importance of the channel between Tresco and Bryher in theIsles of Scilly in the defence of the British Isles has been recognised across the centuries. In 1550, during the reign of Edward VI a small artillery fortress was built on the high ground of Tresco. Its purpose was to defend the harbour of New Grimsby. At the beginning of the Civil War it was garrisoned by Royalist troops. It later became known as King Charles’s Castle.
However, the site of the fortress was considered unsuitable and when the Parliamentarians gained power a new artillery tower was built on the rocky shore in 1651. Its purpose was to defend against all threats – notably, at that time, from the Dutch.

During our recent holiday on Tresco, one of the Isles of Scilly, we were fortunate to have accommodation that looked out across the channel separating Tresco from Bryher. The crossing of the channel at the times of the Spring tides was shown in an earlier post. (See https://lagill6.wordpress.com/2018/10/23/spring-tide-adventurers/)

There seems to be a suggestion of tapestry design in this image of lichen photographed on a rock on St Agnes in the Isles of Scilly. The natural pattern is recorded as found. The only licence taken has been the removal of the texture of the granite rock to reveal the pattern more clearly..
