Fortifications: Why walls of stone and not of earth?

[Peroni]

Landguard Fort in my home town... Very similar design..a seven casemated battery.

"Overlooking the Orwell Estuary, the Fort has a long and rich history. Originally a fort was built at the behest of Henry VIII. The later fort of 1625 was the last fort in England to oppose a full scale invasion. It was on 2nd July (Julian Calendar) in 1667 when Captain Nathaniel Darell and 400 of the Duke of York & Albany's Maritime Regiment, with 100 gunners and 51 cannon, successfully repelled Admiral de Ruyter's Dutch force of 2 to 3 thousand! It is still remembered today".

I have Dutch ancestry, perhaps my ancestor was taken prisoner during this battle?

The photo of the turf and timber reconstruction of the Lunt Roman fort, Baginton (Above) 'Lunt Now' is slightly out of date, as the gate house has been fully repaired and is accessible to the public. The rest of the rampart has however been left to dissintegrate!
