One of the greatest of these great castles, Riegersbourg, was refortified in the days of Pope and Addison.
It was refortified by the celebrated Dutch general of engineers, Coehoorn, in the beginning of the 18th century.
This is an error, as the fort was neither rebuilt nor refortified.
early 15c., "increase efficacy" (of medicine); mid-15c., "provide (a town) with walls and defenses," from Old French fortifiier (14c.) "to fortify, strengthen," from Late Latin fortificare "to strengthen, make strong," from Latin fortis "strong" (see fort) + facere "to make" (see factitious).
Sense of "to strengthen mentally or morally" is from late 15c. Meaning "add liquor or alcohol" is from 1880. Related: Fortified; fortifying.
