Its rare triangular moated plan, unique among British castles, encloses four centuries of Maxwell power and border warfare, from Edward I's siege of 1300 to the Covenanter slighting of 1640.

A moated stronghold on the Solway shore, Caerlaverock Castle takes a triangular plan unlike that of any other castle in Britain, some eleven kilometres south of Dumfries at the edge of the Caerlaverock National Nature Reserve. First built in the thirteenth century and said to have been sited to control trade, it was a stronghold of the Maxwell family from the 1200s until the 1600s. It was besieged by the English during the Wars of Scottish Independence and underwent several partial demolitions and reconstructions across the fourteenth and fifteenth centuries. In the seventeenth century the Maxwells, created Earls of Nithsdale, added a new lodging within the walls, counted among the most ambitious early classical domestic architecture in Scotland. Besieged for the last time by a Covenanter army in 1640, it was then abandoned. Historic Environment Scotland now cares for the scheduled monument.

What follows is drawn from published sources, with each claim labelled by how firmly it is established.

The name

The name Caerlaverock is of Brittonic origin. The first element, cajr (Welsh caer, 'fort, city'), means an enclosed, defensible site; the second may be a personal name or a lost stream-name from the adjective laβar, 'talkative'. The present form has been influenced by the Scots word laverock, 'skylark'.

History

Around 1220, Alexander II of Scotland granted the lands to Sir John Maxwell, who began the first castle at Caerlaverock — a square structure and one of the earliest stone castles in Scotland.

In the 1270s Sir Aymer Maxwell completed the present triangular castle on a rock outcrop some 200 metres north of the abandoned first castle.

In July 1300, Edward I of England besieged Caerlaverock; the Maxwell garrison of only sixty men, under Sir Eustace Maxwell, withstood the English army for a considerable period before surrendering.

Around 1355 Sir Roger Kirkpatrick of Closeburn captured the castle for David II of Scotland and partly dismantled it.

In 1570 an English Protestant force led by the Earl of Sussex besieged and partly demolished the castle, destroying the gatehouse with gunpowder.

In 1640 a Protestant Covenanter army besieged Caerlaverock for thirteen weeks, forcing its surrender; the south wall and tower were demolished and the castle was never repaired or reoccupied.

    Caerlaverock National Nature Reserve

    The castle stands at the northern edge of this 55-square-kilometre reserve of saltmarsh and mudflats, an internationally important wintering site for waterfowl

In culture

  • During the 1300 siege, English heralds composed a roll of arms in Old French verse, known as the Siege of Caerlaverock, naming each noble and knight present and describing his armorial bearings.

  • The castle was used as a filming location for the 2011 romantic comedy The Decoy Bride.

What to look for

  • The triangular plan enclosed by a moat and earthwork ramparts, one of only a few in Europe and the only such castle in the UK

  • The twin-towered gatehouse at the northern apex, its ashlar drum towers standing some 15.5 metres to the late-fifteenth-century machicolations

  • Murdoch's Tower at the south-west corner, largely complete, contrasting with the south-east tower reduced to base level in the 1640 siege

  • The Nithsdale Lodging's Renaissance façade of the 1630s, decorated with carved pediments over its windows bearing armorials and symbolic sculptures

  • The red sandstone of the earliest parts, quarried nearby at Bankend

What is said

Folklore and tradition, recorded as what is said — not as established fact.

  • King Gwenddoleu ap Ceidio died near Caerlaverock at the Battle of Arthuret in 573, and his death drove his bard Myrddin Wyllt to madness and into the woods — an act later said to have inspired the character of Merlin in Arthurian legend.
