MMostyn is a small village in Flintshire, North Wales, lying on the estuary of the River Dee, and located near to the town of Holywell.
Mostyn once served as a port from which ferries used to sail (until 2004) to Dublin on the Liverpool-Dublin route. Today, manufactured wings for the massive A380 aircraft leave Mostyn on the ship Ville De Bordeaux, after travelling up the River Dee by barge from the Airbus wing factory at Broughton, Flintshire.
Mostyn's port area is home to the headquarters of Warwick International Group Limited, manufacturer's of bleach activators for detergent applications.
Mostyn was also home to the famous, but now closed Mostyn Fun Ship. The ship started life as The Duke of Lancaster, a car ferry and cruise ship. After it was permanently dry-docked in Mostyn it earned its later name from its new operation as an arcade and bar.
