The Isle of Man, fort by fort.
From Iron Age hillforts and promontory forts to Castle Rushen, Peel Castle and a Tudor fort: who built them and when, how they worked, and the open questions. Every fact is checked against Manx National Heritage, Visit IOM, two 2002 papers from the Scottish Society for Northern Studies and other sources, and where sources disagree we show each one.
The short version
It sits in the middle of the Irish Sea, between England, Scotland, Ireland and Wales. Manx National Heritage: About the Isle of Man The island has a 10,000-year history, with a strong Celtic and Viking past. Manx National Heritage: About the Isle of Man
Iron Age sites on the island include the hillforts at South Barrule and Cronk Sumark and the coastal forts of Cronk ny Merriu, Close ny Chollagh and Burroo Ned. Manx National Heritage (archived gov.im page, 2012): Celtic Farmers, Iron Age
Castle Rushen in Castletown is one of the best-preserved medieval castles in the British Isles. Manx National Heritage: Castle Rushen Peel Castle stands on St Patrick’s Isle, joined to Peel by a causeway. Visit IOM: Peel Castle
Andrew Johnson suggests the reused forts were lookout posts in a coastal watch called the Watch and Ward. Andrew Johnson, “Watch and Ward on the Isle of Man” (Scottish Society for Northern Studies, 2002)

A castle built in stages
The first stage, around 1200, was a great tower inside a ditch. Manx National Heritage: Castle Rushen Assessment of Significance (2017), on Planning Portal IoM In the 1330s and 1340s the tower was raised and towers were added to the south, west and east. Manx National Heritage: Castle Rushen Assessment of Significance (2017), on Planning Portal IoM From the 1360s to the 1390s came the curtain wall, gatehouse, barbican and a new ditch.

And a castle on an island
It is the biggest and most complex heritage site on the island, inside a 700-metre curtain wall. Manx National Heritage: Peel Castle Inside are almost two hectares of fortifications built over 700 years, with a cathedral, a church, chapels and graveyards.
