So, technically, it is now April - but here is the March 2011 AOTM. Apologies for late arrival.

This month Lucy Gibbon brings us a document from the Melsetter Estate Records associated with the building of a battery and two Martello Towers to guard the anchorage at Longhope, Hoy.

Also included, a photograph taken of the Martello tower at Hackness from the archives, and David Mackie has kindly contributed a brief history of the Hackness Battery and the Martello Towers.
