Not enough cycling this last few weeks, just an occasional spin.
One cycle took me by historic Banagher in Offaly located on the banks of the River Shannon.
Cromwell's Castle is an old fortification right on the edge of the Shannon and there's an old Martello Tower there too.
Unfortunately the Martello Tower is located on private property in someone's garden.
There towers were built to withstand direct cannon fire with massively thick walls and are usually to be found on seafront locations. There's a few along the River Shannon which I presume underscores British fears of a French fleet sailing up the Shannon.
Hopefully this week see's more Bike time.......
