This postcard is of The Martello Tower. Immortalised by James Joyce in the novel 'Ulysses'.
The tower, one of several along the coast were originally built to protect against the possibility of invasion by Napoleon. It is now a museum and contains some of James Joyce's personal possessions.
There is something about Ireland...probably because my ancestors came from there. Whatever it is, I have always wanted to go there. For now, it looks like I'll have to settle for the postcards!! No trips planned any time soon! Maybe when we retire!
