The Mint is a fortified house and National Monument located in Carlingford, County Louth, Ireland.

[5][6][7] This castle, variously called a fortified house or tower house, derived its name from the license to mint coins granted to Carlingford in 1467 by Edward IV.

It is believed to have housed one of Carlingford's wealthy merchant families (perhaps the Marmions[7]); however, the lack of a fireplace and the strength of the defences suggest that it may indeed have served as a mint.

There is a battlemented chemin de ronde on the roof, with loopholes for muskets.

The ground and first storey ogee windows (five in total) face onto the street, with carvings of a horse, a bust of a man, a bird, a snake and Celtic interlace ornament which reflects a revival of interest in Celtic art in the 15th–16th centuries.
