Suddery is a small town (claiming to be a city, having once been the seat of the Bishop of Sodor), the ancient capital and seat of the Sodor Regiment. Its motto is "Luoc Sodoris Lux", or, translated from Latin, "Luoc, the Light of Sodor". 

In the 5th century Luoc, who was an Irish Missionar from the "St. Patrick's school" stranded in Suddery Bay. He and his companions preached to the local natives and built a "keeill", which later became Suddery Cathedral.  

In the 11th Century three Bishops ruled in Suddery. But after a resolution the Diocese of Sodor and the of Man were merged into one.  

Suddery was once a fortified town, with a castle being a late addition. The site was refortified in Napoleonic times, but its appearance has not been spoilt by the new additions, namely several batteries built then.      

Suddery was connected by the Wellsworth and Suddery Railway via rail with Brendam and Crosby in 1870.

The Suddery station has two platforms before the level crossing ended with the sidings and the goods shelters.

The North Western Railway's main line bypasses the town of Suddery as it climbs Gordon's Hill to the north, but there is a station serving the town on Edward's Branch Line.
