This hamlet lies at the junction of the Scarborough and Filey roads, which unite before passing through Seamer on their way to York and Driffield.

A ruined fragment of wall containing a 15th-century doorway is now all that is standing above ground, but extensive foundation mounds may be traced in connexion with it.

The Star Carr house was comparable to an Iron Age roundhouse, about 3.5 metres (11 ft) wide and made of wood.

[7] The summer of 1603 was an exceptionally long one, which prolonged the presence of the plague to the north of Seamer in Whitby, Robin Hoods Bay and Harwood Dale.

Mompesson also petitioned the Earl of Salisbury to grant him the parsonage of Seamer and the chapels of Cayton and East Ayton.

[10] Following Charles I's failure in the Second Bishops' War in 1640, the defeated English army had not been paid and instead were forcibly billeted in parts of Yorkshire.

An outrage occurred when in 1640, the only local landowning gentleman, Roger Wyvill, spotted four of Canaervon's soldiers attacking a traveller in Seamer, and tried to intervene.

"[11] When the English Civil War broke out in August 1642, Sir Hugh Cholmeley, 1st Baronet, the MP for Scarborough, was sent north by Parliament to put the town in a state of readiness.

Following the Battle of Marston Moor in July 1644, and the Parliamentarian capture of York, Scarborough became the most important Royalist stronghold in Yorkshire.

The owner of Seamer throughout this period remained Sir Robert Napier, who was a Royalist and whose estates in Bedfordshire and "presumably elsewhere" had been sequestered by Parliament.

[12] In February 1645, Sir John Meldrum captured the town, and began the siege of the castle, which concluded in a Parliamentarian victory on 25 July.

By the middle of the twelfth century the original wooden Saxon church had been replaced with a stone building with a tower which served as a minor castle.

They broke into the house, captured the owner, Mr. Clapton, his brother-in-law, Mr. Richard Savage, sheriff of York, and a manservant, and carried them off to the Wolds, where they were stripped and murdered.

[14] With the establishment of the railway and the increase in public and private transport the quiet, peaceful parish of Seamer was ripe for expansion after the First World War.

Large housing developments have taken place at Seamer and Crossgates since the 1960s and an industrial estate now occupies the south-eastern corner of the parish.
