Royal Welch Fusiliers Museum

Three centuries of Welsh military history unfold within the medieval walls of Caernarfon Castle, where the Royal Welch Fusiliers Museum occupies the Queen's Tower. The regiment's story spans from 1689 to the present day, told through an impressive collection of uniforms, medals, weapons and personal effects.

History buffs will find themselves absorbed by the Victoria Crosses on display - eleven in total, more than any other Welsh regiment earned. The museum doesn't shy away from the grittier realities of warfare either. Personal letters home and trench art from the Somme bring the human cost into sharp focus.

Families staying at nearby Glan Gwna Holiday Park or Coed Helen will find this works well as part of a castle visit. The museum sits within Caernarfon Castle itself, so you're getting two attractions for the price of one really. Kids might find the military displays a bit dry after the first room, but the interactive elements help keep their attention.

Allow about an hour for a thorough look around, though military enthusiasts could easily spend longer poring over the medals and regimental silver. The location within the castle means you'll want to check opening times for both attractions before making the trip across from your park base.
