Hen Capel Lligwy is a ruined 12th century, Grade II listed chapel located in Lligwy, Anglesey.
Capel Lligwy was first built sometime in the first half of the 12th century. Due to the chapels location, its purpose is unclear and may have been a chapel of ease rather than becoming a parish church in its own right.
By the 14th century the chapel was partially rebuilt and possibly enlarged as the upper walls date from that time. In the 16th century the chapel was expanded by adding another chapel to the south side which included a vault. The vault was used by the Pierce Lloyd, who owned the nearby Lligwy House, to bury their dead.
By the early 18th century the chapel was abandoned and left with no roof, falling into disrepair.
In 1999, the vault was used to record some 'atmospheres' for the album 'You Have Just Been Poisoned By The Serpents' by The Serpents, a collective of Welsh musicians including members of Echo and the Bunnymen, Super Furry Animals and Ectogram that was described by one journalist as "possibly the strangest pop group of all time".
Today the chapel is in the care of Cadw.
