Tresco

Oliver's Battery - Crow Point, South Tresco, just behind Carn Near.  [sah 71, p51]  This was the fort/battery constructed by Admiral Blake's forces from which he could bombard St Mary's Pool.  It is of pentagonal shape on top of a rocky knoll.  Unlike the Royalist emplacement lower down the hill this structure was designed for guns to fire west, north-west and north-east. It must have been built sometime between the 18 April 1651 when they captured Tresco and 23 May when the Royalist on the Garrison finally surrendered.

The Blockhouse, referred to as Dover Fort (Parliamentary Survey 1652).  Certainly used in the Civil War.

Charles Castle (King Charles) - Built c. 1550 to protect New Grimsby Harbour, Tresco.  At one time it could accommodate two levels of gun armament.  The castle was however badly-sited.  For authoritative remarks on the Castle Down fortifications see [sah 68, p48]
