Annagassan (Irish: Áth na gCasán, meaning 'ford of the paths')[2] is a village in the townland of Ballynagassan, County Louth, Ireland.

These early raids were sporadic coastal attacks by small seaborne forces; however, from the 830s, a new phase was characterised by larger fleets, which penetrated up navigable rivers and plundered extensive inland areas.

[9] The modern village is generally believed to be built on what some archaeologists consider to be a man-made polder structure, constructed to provide shelter for the fjord.

The original settlement was located further upstream; navigation was considerably easier on the River Glyde in the 9th century before the intervening build-up of sediment.

[citation needed] In sport, the local GAA club, Naomh Fionnbarra and St Anne's GFG, compete in Gaelic football competitions.

The club fields children's, men's and women's teams and plays its home matches at John Markey Park in Annagassan.
