A yellow Independence Day flag is flying over Sigginstown Castle as I approach. It is proof that the once green, mouldy-walled ruin in Tacumshane that my contractor husband once tilled the fields around has come to life again – and that Connecticut couple, Liz and Gordon Jones, are at home. The tower is now practically finished, they are living in the adjoining big house and new life has been breathed into this sixteenth-century heritage building that was once a defence structure to keep an eye out for coastal, marauding invaders coming in off Carne or Rosslare.
